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

TPGC12C-1 from TECH PUBLIC, in a SOD-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 (line terminal) | passive | One terminal of the bidirectional TVS diode, with a nominal reverse working voltage of 12V (max) and a reverse leakage of 0.2µA max at VRWM = 12V. |
| 2 | Pin 2 (line terminal) | passive | The other terminal of the bidirectional TVS diode, with a clamping voltage of 18V max at IPP = 1A and 29V max at IPP = 12A (8 x 20µs pulse). |
