# SRV05-4-ES

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

SRV05-4-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; one of four unidirectional ESD-protected lines, with the device rated for a 5V working voltage (VRWM). |
| 2 | GND | power_in | Connect to GND, the common ground reference for the ESD clamps. |
| 3 | IO2 | bidirectional | Connect to I/O; one of four unidirectional ESD-protected lines, with the device rated for a 5V working voltage (VRWM). |
| 4 | IO3 | bidirectional | Connect to I/O; one of four unidirectional ESD-protected lines, with the device rated for a 5V working voltage (VRWM). |
| 5 | Vcc | power_in | Connect to Vcc, the supply pin of the protection device. |
| 6 | IO4 | bidirectional | Connect to I/O; one of four unidirectional ESD-protected lines, with the device rated for a 5V working voltage (VRWM). |
