# UDD32C15L01

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

UDD32C15L01 from Brightking, 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 | One terminal of the two-terminal TVS array (steering-diode bridge with internal TVS diode), 15V reverse stand-off (VRWM), 16.7V min breakdown at 1mA, 0.8pF typical junction capacitance, ±8kV contact / ±15kV air ESD rated. |
| 2 | 2 | passive | Other terminal of the two-terminal TVS array, drawn symmetrically to pin 1 in the pin configuration diagram, with the same 15V stand-off and ESD ratings, so it is connected in line with or across the protected line. |
