82402374

Wurth Elektronik · Electrostatic And Surge Protection (TVS/ESD) · SC-70-5

82402374 from Wurth Elektronik, in a SC-70-5. 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 I/O_1 passive Channel 1 signal I/O line. Unidirectional TVS diode is connected from this pin to GND (pin 2), clamping positive transients above ~6V breakdown and shunting negative transients through the forward diode (VF ~0.8V @ 15mA).
2 GND passive Common ground / cathode reference return for all four TVS channels. Must be connected to system ground with a low-inductance path for effective ESD/surge diversion.
3 I/O_2 passive Channel 2 signal I/O line. Unidirectional TVS diode is connected from this pin to GND (pin 2), clamping positive transients above ~6V breakdown and shunting negative transients through the forward diode.
4 I/O_3 passive Channel 3 signal I/O line. Unidirectional TVS diode is connected from this pin to GND (pin 2), clamping positive transients above ~6V breakdown and shunting negative transients through the forward diode.
5 I/O_4 passive Channel 4 signal I/O line. Unidirectional TVS diode is connected from this pin to GND (pin 2), clamping positive transients above ~6V breakdown and shunting negative transients through the forward diode.
