JEDEC registered package outline
Complies with the following standards
IEC 61000-4-2 level 4:
15 kV (air discharge)
8 kV (contact discharge)
MIL STD 883G, method 3015-7: class 3B:
25 kV HBM (human body model)
Description
The SMA6J Transil series has been designed to
protect sensitive equipment against electro-static
discharges according to IEC 61000-4-2, MIL STD
883 Method 3015, and electrical overstress such
as IEC 61000-4-4 and 5. They are generally for
surges below 600 W 10/1000 μs.
This planar technology makes it compatible with
high-end equipment and SMPS where low
leakage current and high junction temperature
are required to provide reliability and stability
over time. Their low clamping voltages provides a
better safety margin to protect sensitive circuits
with extended life time expectancy.
Packaged in SMA, this minimizes PCB space
consumption (SMA footprint in accordance with
IPC 7531 standard).

Notes:
(1)Pulse test: tp < 50 ms
(2)To calculate VBR or VCL versus junction temperature, use the following formulas:
VBR at TJ = VBR at 25 °C x (1 + αT x (TJ - 25))
VCL at TJ = VCL at 25 °C x (1 + αT x (TJ-25))
(3)To calculate maximum clamping voltage at other surge level, use the following formula:
VCLmax = VBR max + RD x IPPappli where IPPappli is the surge current in the application
(4)Surge capability given for both directions for unidirectional and bidirectional types.
