SRV05-4A-ES

ElecSuper · ESD And Surge Protection (TVS/ESD) · SOT-23-6L

SRV05-4A-ES from ElecSuper, in a SOT-23-6L. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 IO1 bidirectional Connect to I/O; this is one of the four unidirectional ESD-protected lines, rated for a 5 V working voltage (VRWM).
2 GND power_in Connect to GND, the ground reference for the protection clamps.
3 IO2 bidirectional Connect to I/O; this is one of the four unidirectional ESD-protected lines, rated for a 5 V working voltage (VRWM).
4 IO3 bidirectional Connect to I/O; this is one of the four unidirectional ESD-protected lines, rated for a 5 V working voltage (VRWM).
5 Vcc power_in Connect to Vcc, the supply pin of the device; the datasheet gives no separate Vcc voltage limit beyond the 5 V working voltage.
6 IO4 bidirectional Connect to I/O; this is one of the four unidirectional ESD-protected lines, rated for a 5 V working voltage (VRWM).
