1N4148W-HE3-18 from Vishay Intertech, 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, the terminal marked by the cathode bar on the SOD-123 body; reverse voltage VR is 75 V max and repetitive peak reverse voltage VRRM is 100 V max. |
| 2 | A | passive | Anode, the terminal opposite the cathode bar; average rectified current IF(AV) is 150 mA max and surge forward current IFSM is 500 mA (tp < 1 s). |
