# TPGBLC15C

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

TPGBLC15C 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 | I/O 1 | passive | Bi-directional TVS terminal 1 (protected line side), rated for 15.0 V max reverse working voltage and ±30 kV IEC 61000-4-2 air/contact ESD. |
| 2 | I/O 2 | passive | Bi-directional TVS terminal 2 (opposite side of the protected line or ground return), interchangeable with pin 1 since the device is bi-directional with 1.0 pF typical capacitance. |
