# ESDA6V1W5

**TECH PUBLIC** · ESD And Surge Protection (TVS/ESD) · SOT-353-5

ESDA6V1W5 from TECH PUBLIC, in a SOT-353-5. 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 | I/O1 | passive | TVS protected line 1 (I/O), steering-diode clamp to GND on pin 2; reverse working voltage 5V max, breakdown 6V to 9V at 1mA. |
| 2 | GND | power_in | Common ground return for the TVS array, shared by all four protected lines. |
| 3 | I/O2 | passive | TVS protected line 2 (I/O), steering-diode clamp to GND on pin 2; reverse working voltage 5V max, breakdown 6V to 9V at 1mA. |
| 4 | I/O3 | passive | TVS protected line 3 (I/O), steering-diode clamp to GND on pin 2; reverse working voltage 5V max, breakdown 6V to 9V at 1mA. |
| 5 | I/O4 | passive | TVS protected line 4 (I/O), steering-diode clamp to GND on pin 2; reverse working voltage 5V max, breakdown 6V to 9V at 1mA. |
