# TPPEC2605C2C

**TECH PUBLIC** · ESD And Surge Protection (TVS/ESD) · SOT-323

TPPEC2605C2C from TECH PUBLIC, in a SOT-323. 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 | PIN 1 | passive | TVS diode line terminal 1 (bi-directional, 5V operating voltage, VRWM max 5V), connected through a TVS element to common pin 3. |
| 2 | PIN 2 | passive | TVS diode line terminal 2 (bi-directional, 5V operating voltage, VRWM max 5V), connected through a TVS element to common pin 3. |
| 3 | PIN 3 | passive | Common terminal joining the two TVS elements from pins 1 and 2 in the pin-configuration diagram. |
