YFW · Diodes - General Purpose · SOD-323
SM4001WS from YFW, in a SOD-323. 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 terminal of the rectifier diode (pin 1 per the pinning table); reverse voltage rating 50 V to 1000 V depending on the SM4001WS-SM4007WS type. |
| 2 | Anode | passive | Anode terminal of the rectifier diode (pin 2 per the pinning table); average forward current 1 A with maximum forward voltage 1.1 V at 1 A. |
