Transient Threats – What Are Transients?
Voltage Transients are defined as short duration surges of
electrical energy and are the result of the sudden release
of energy previously stored or induced by other means,
such as heavy inductive loads or lightning. In electrical
or electronic circuits, this energy can be released in a
predictable manner via controlled switching actions, or
randomly induced into a circuit from external sources.
Repeatable transients are frequently caused by the
operation of motors, generators, or the switching of
reactive circuit components. Random transients, on the
other hand, are often caused by Lightning and Electrostatic
Discharge (ESD). Lightning and ESD generally occur
unpredictably, and may require elaborate monitoring to be
accurately measured, especially if induced at the circuit
board level. Numerous electronics standards groups have
analyzed transient voltage occurrences using accepted
monitoring or testing methods. The key characteristics of
several transients are shown in the table below.
VOLTAGE CURRENT RISE-TIME DURATION
Lighting 25kV 20kA 10 µs 1ms
Switching 600V 500A 50µs 500ms
EMP 1kV 10A 20ns 1ms
ESD 15kV 30A <1ns 100ns
Table 1. Examples of transient sources and magnitude
Characteristics of Transient Voltage Spikes
Transient voltage spikes generally exhibit a “double
exponential” wave, as shown below for lightning and ESD.

Figure 2. ESD Test Waveform
The exponential rise time of lightning is in the range
1.2µsec to 10µsec (essentially 10% to 90%) and the
duration is in the range of 50µsec to 1000µsec (50% of
peak values). ESD on the other hand, is a much shorter
duration event. The rise time has been characterized at less
than 1.0ns. The overall duration is approximately 100ns.
Why are Transients of Increasing Concern?
Component miniaturization has resulted in increased
sensitivity to electrical stresses. Microprocessors for
example, have structures and conductive paths which
are unable to handle high currents from ESD transients.
Such components operate at very low voltages, so
voltage disturbances must be controlled to prevent device
interruption and latent or catastrophic failures.
Sensitive microprocessors are prevelant today in a wide
range of devices. Everything from home appliances, such
as dishwashers, to industrial controls and even toys use
microprocessors to improve functionality and efficiency.
Most vehicles now also employ multiple electronic
systems to control the engine, climate, braking and, in
some cases, steering, traction and safety systems.
Many of the sub- or supporting components (such as
electric motors or accessories) within appliances and
automobiles present transient threats to the entire system.
Careful circuit design should not only factor environmental
scenarios but also the potential effects of these related
components. Table 2 below shows the vulnerability of
various component technologies.

Electrostatic Discharge (ESD)
Electrostatic discharge is characterized by very fast
rise times and very high peak voltages and currents.
This energy is the result of an imbalance of positive and
negative charges between objects.
ESD that is generated by everyday activities can far surpass
the vulnerability threshold of standard semiconductor
technologies. Following are a few examples:
• Walking across a carpet:
35kV @ RH = 20%;1.5kV @ RH = 65%
• Walking across a vinyl floor:
12kV @ RH = 20%;250V @ RH = 65%
• Worker at a bench:
6kV @ RH = 20%;100V @ RH = 65%
• Vinyl envelopes:
7kV @ RH = 20%;600V @ RH = 65%
• Poly bag picked up from desk:
20kV @ RH = 20%;1.2kV @ RH = 65%
Lightning Induced Transients
Even though a direct strike is clearly destructive, transients
induced by lightning are not the result of a direct strike.
When a lightning strike occurs, the event creates a
magnetic field which can induce transients of large
magnitude in nearby electrical cables.
A cloud-to-cloud strike will
effect not only overhead cables,
but also buried cables. Even a
strike 1 mile distant (1.6km) can
generate 70 volts in electrical
cables.
In a cloud-to-ground strike (as
shown at right) the transient-
generating effect is far greater.
This diagram shows a typical
current waveform for induced
lightning disturbances.
Inductive Load Switching
The switching of inductive loads generates high energy
transients which increase in magnitude with increasingly
heavy loads. When the inductive load is switched off, the
collapsing magnetic field is converted into electrical energy
which takes the form of a double exponential transient.
Depending on the source, these transients can be as large
as hundreds of volts and hundreds of Amps, with duration
times of 400 milliseconds.
Typical sources of inductive transients include:
•Generator •Motor
•Relay •Transformer
These examples are common in electrical and electronic
systems. Because the sizes of the loads vary according
to the application, the wave shape, duration, peak current
and peak voltage are all variables which exist in real world
transients. Once these variables can be approximated, a
suitable suppressor technology can be selected.
The diagram at right shows a
transient which is the result
of stored energy within the
alternator of an automobile
charging system.
A similar transient can also be
caused by other DC motors
in a vehicle. For example,
DC motors power amenities
such as power locks, seats
and windows. These various
applications of a DC motor can produce transients that are
just as harmful to the sensitive electronic components as
transients created in the external environment.

TVS Diode FIT Calculation Method
Reference
JEDEC JESD 85, methods for calculating failure rates in
units of FITs
JEDEC JESD 91A, method for developing acceleration
models for electronic component failure mechanisms.
Life Test
FIT is calculated based on life test result.
Littelfuse conducts Blocking test as following condition at
any qualification or on-going reliability monitoring activity.
Temperature: 150°C, Duration: 504 hours, Sample number:
40
Note, this is minimum requirement and the duration and
sample number could be increased per test purpose.
Acceleration Factor
Acceleration Factor or AT is calculated per JEDEC JESD
91A, Arrhenius equation with Eaa (activation energy) of
1.0eV by dielectric breakdown mechanism.
AT = exp[(-Eaa/k)(1/Tt - 1/ Ts )]
AT: the acceleration factor due to changes in temperature
Eaa: the apparent activation energy (eV)
k: Boltzmanns constant (8.62 × 10-5 eV/K)
Tt: the absolute temperature of the test (K)
Ts: the absolute temperature of the system (K)
From the life test, Tt = 150°C, assuming Ts = 30°C,
acceleration factor is
AT = exp[(-1/8.62 × 10-5)(1/(150+273.16) - 1/(30+273.16)]
= 5.2 × 104
Failure Rate Calculation
Failure rate or λCL is calculated per JEDEC JESD 85, using
the upper confidence bound of the failure rate.
λCL = X2(CL, 2f+2) × 109 / (2 × t × ss × A)
λCL: Failure rate in FIT
X2: Chi-square distribution function
CL: confidence level
f: number of failures
t: test time in hours
ss: number of samples
A: acceleration factor
From life test result, f=0, t= 504 hours, ss =40.Assuming
Ts=30°C, and using CL=60%, failure rate is
λCL = X2(60%, 2) × 109 / (2 × 504 × 40 × 5.2 × 104)
= 1.897 × 109 / (2 × 504 × 40 × 5.2 × 104)
= 0.9 FIT
Note: the published reliability test report usually rounds up
the failure rate to 1 FIT at 30°C.

TVS Diode Selection Checklist
1. Define Circuit Operating Parameters
Normal operating voltage type in DC or AC:
Device Type Required: Uni-drectional Bi-directional
Normal operating voltage in volts:
Maximum transient current (Ipp):
Maximum clamping voltage (Vc):
Required peak reverse surge power rating:
Product mounting type (package):
Operating temperature:
2. Narrow TVS Diode Series for the Application
Please refer to the product selection charts and data
sheets within this guide, factoring these key parameters:
Reverse Standoff Voltage (VR):
The device VR should be equal to, or great than, the
peak operating level of the circuit (or part of the circuit)
to be protected. This is to ensure that TVS Diode does
not clip the circuit drive voltage.
Peak Pulse Current (IPP):
The Peak Pulse Current (IPP) identifies the maximum
current the TVS Diode can withstand without damage.
The required IPP can only be determined by dividing the
peak transient voltage by the source impedance. Note
that the TVS Diode failure mechanism is a short circuit; if
the TVS Diode fails due to a transient, the circuit will still
be protected.
Maximum Clamping Voltage (VC):
This the peak voltage that will appear across the TVS
Diode when subjected to the Peak Pulse Current (IPP),
based on 10/1000µs exponential waveform. The VC of
each TVS Diode is identified in each series data sheet
electrical characteristics table.
3. Verify Ambient Operating Parameters
Ensure that the application voltage is less than or equal
to the devices standoff voltage, and that the operating
temperature limits are within those specified by the device.
4. Verify Device Mounting Style and Dimensions
Please refer to the dimension drawings contained within
the data sheet of each series.
5. Test the Selected Device in Actual Application
Please contact Littelfuse if you would like assistance
with testing and verifying suitability of a Littelfuse device
within your product. We have extensive product testing lab
capabilities and technical expertise to assist you.
Clamping Device
TVS is a clamping device that limits voltage spikes by low
impedance avalanche breakdown of a rugged silicon PN
junction. It is used to protect sensitive components from
electrical overstress generated by induced lightning, inductive
load switching and electrostatic discharge.
Operating Temperature Range
The minimum and maximum ambient operating temperature
of the circuit in which a device will be applied. Operating
temperature does not allow for the effects of adjacent
components, this is a parameter the designer must take into
consideration.
Capacitance
The property of a circuit element that permits it to store
an electrical charge. In circuit protection, the off-state
capacitance is typically measured at 1 MHz.
Reverse Standoff Voltage (VR)
In the case of a uni-directional TVS diode, this is the
maximum peak voltage that may be applied in the ‘blocking
direction’ with no significant current flow. In the case of
a bi-directional transient, it applies in either direction. It is
the same definition as Maximum Off-state Voltage and
Maximum Working Voltage.
Breakdown Voltage (VBR)
Breakdown voltage measured at a specified DC test current,
typically 1mA. Usually a minimum and maximum is specified.
Peak Pulse Current (IPP)
Maximum pulse current which can be applied repetitively.
Usually a 10/1000µs double exponential waveform, but can
also be 8/20µs, if stated.
Maximum Clamping Voltage (VC or VCI)
Maximum voltage which can be measured across the
protector when subjected to the Maximum Peak Pulse
Current.
Peak Pulse Power (PPP)
Expressed in Watts or Kilowatts, for a 1ms exponential
transient (see figure 1, page 31) it is IPP multiplied by VCL.
