PSM712-ES

ElecSuper · ESD And Surge Protection (TVS/ESD) · SOT-23

PSM712-ES from ElecSuper, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 IO passive Bidirectional protected I/O line. Connects to the signal line being protected against ESD/EFT transients. VRWM = 12V (pin1/2 to pin3), clamping voltage ~24V at IPP=17A.
2 IO passive Bidirectional protected I/O line. Connects to the signal line being protected against ESD/EFT transients. VRWM = 12V (pin1/2 to pin3), clamping voltage ~24V at IPP=17A.
3 GND passive Ground / reference return. Connects to the system ground and serves as the reference node for the internal TVS structure. VRWM = 7V from pin 3 to pin 1/2; clamping voltage ~18V at IPP=22A.
