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. |
