1N4148W-G3-08 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 at the end marked with the cathode bar on the SOD-123 package; the diode is reverse-rated to VR 75 V (VRRM 100 V). |
| 2 | A | passive | Anode, the terminal at the end opposite the cathode bar; average rectified current IF(AV) is 150 mA and surge forward current IFSM is 500 mA (t < 1 s). |
