SMF12A from AnBon, 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 of the unidirectional SMF12A, marked by the cathode band; reverse standoff voltage 12 V, breakdown 13.3 V min to 14.7 V max at 1.0 mA, max clamping 19.9 V at 10.1 A. |
| 2 | A | passive | Anode of the unidirectional SMF12A, on the side opposite the cathode band, with 200 W peak pulse power (10x1000 us) rating for the device. |
