SMF14A from DOWO, 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 TVS, marked by the color band; connects to the positive side of the protected line (VRWM 14.0 V, VBR 15.6 to 17.2 V at 1 mA). |
| 2 | A | passive | Anode of the unidirectional TVS, the end without the color band; connects to the ground or return side (max clamping voltage 23.2 V at IPP 8.62 A). |
