Brightking · ESD And Surge Protection (TVS/ESD) · SOD-123
SJD12A33L01 from Brightking, in a SOD-123. 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 | K | passive | Cathode (marked-band end) of the unidirectional TVS diode, connected to the protected I/O line, with VRWM 33.0V, VBR 36.70-40.60V at 1mA, and VC 53.3V at 3.8A IPP. |
| 2 | A | passive | Anode of the unidirectional TVS diode, normally tied to ground, with the device rated for ±8kV contact and ±15kV air ESD per IEC61000-4-2. |
