SMFJ15CA 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 | 1 | passive | Bidirectional TVS terminal (SMFJ15CA, 15 V VRWM, 16.7-18.5 V breakdown at 1.0 mA, 24.4 V max clamping at 8.2 A); no cathode band, so it is interchangeable with pin 2. |
| 2 | 2 | passive | Bidirectional TVS terminal (SMFJ15CA, 15 V VRWM, 16.7-18.5 V breakdown at 1.0 mA, 24.4 V max clamping at 8.2 A); no cathode band, so it is interchangeable with pin 1. |
