# TPGBLC08C

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

TPGBLC08C 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 | 1 | passive | Bi-directional TVS terminal 1 connected to the protected power or data line, with 8.0 V maximum reverse working voltage (VRWM) and 8.5 V minimum breakdown voltage at 1 mA. |
| 2 | 2 | passive | Bi-directional TVS terminal 2 connected to the opposite side (typically ground), with 19.5 V maximum clamping voltage at IPP = 18 A (8x20 µs). |
