The TSDxx are a family of unidirectional TVS protection diodes designed for clamping harmful transients such as ESD and surge. The TSDxx is rated to dissipate ESD strikes up to ±30kV (contact and air gap discharge) and also meets the maximum level specified in the IEC 61000-4-2 international standard (Level 4).

Combining the robust clamping performance and low capacitance of this device, TSDxx is an excellent TVS diode to protect both data and power lines in many different applications.

The TSDxx is offered in the industry standard, leaded SOD-323 package to enable easy solderability.

Evaluation board

ESDEVM — ESD evaluation module

The electrostatic-sensitive device (ESD) evaluation module (EVM) is a development platform for most of our ESD portfolio. The board comes with all traditional ESD footprints in order to test any number of devices. Devices can be soldered onto their respect footprint and then tested. For typical (...)
