# UDD32C24L01

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

UDD32C24L01 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 single-line steering-diode/TVS array, connected to the protected I/O line (24V working voltage, 200W 8/20μs peak pulse power). |
| 2 | 2 | passive | Second terminal of the single-line steering-diode/TVS array, connected to the other side of the protected line (24V working voltage, ±8kV contact / ±15kV air ESD). |
