SJD12A30L01 from FUXINSEMI, 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 | Cathode | passive | Cathode of the unidirectional TVS (marked by the cathode band), connected to the protected I/O line, with 30.0 V reverse stand-off voltage, 33.30 to 36.80 V breakdown at 1 mA and 48.4 V maximum clamping at 4.2 A. |
| 2 | Anode | passive | Anode of the unidirectional TVS, normally connected to ground/return, for a 200 W peak pulse power (10x1000 µs) device. |
