ZHIDE · TVS · SOD-123FL
S4MF15A from ZHIDE, in a SOD-123FL. 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; connect to the positive/protected line (VRWM 15.0 V, VBR 16.70-18.50 V at 1 mA, VC max 24.4 V at IPP 16.4 A). |
| 2 | A | passive | Anode of the unidirectional TVS, the end opposite the color band; connect to ground/return (400 W peak pulse power with a 10/1000 us waveform). |
