Ethernet ESD Protection

Ethernet is everywhere - from telecommunications backhaul to computing connectivity to industrial networking. Ethernet has become a dominant communication standard in the electronics industry. These ports are routinely struck by fast transient ESD threats as well as longer duration lightning pulses. State of the art protection solutions are needed to adequately safeguard these interfaces from the many overvoltage threats. Semtech is leading the way in providing low-clamping voltage, low-capacitance Ethernet protection arrays.

RS-485 ESD Protection

RS-485 has long been a workhorse communication standard for industrial and communications electronics. RS-485 is still widely prevalent today for its advantages in robust, high noise immunity electrical communication. From high-end base stations to surveillance to HVAC control to POS terminals to industrial networks, RS-485 is everywhere. The harsh environments and long distances over which RS-485 links run mean that they are often assaulted with a broad range of electrical transient spikes. Semtech makes highly differentiated TVS protection to safeguard RS-485 ports from the most harsh electrical conditions.

HDMI ESD Protection

High Definition Multimedia Interface (HDMI) is an uncompressed, all-digital audio/video interface. It provides a high speed interface between audio/video source devices, such as DVD players, and sink devices, such as digital displays. The HDMI plug is frequently exposed to Electrostatic Discharge (ESD) directly from the user or Cable Discharge (CDE) from hot plug cable. Semtech has long been a leader in providing high performance ESD protection to both safeguard HDMI silicon from transient threats while also preserving signal integrity on the high-speed interface.
