PANJIT International · Switching Diodes · SOD-123
1N4148W-AU from PANJIT International, 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 | Cathode | passive | Cathode terminal (pin 1 in the datasheet pinout); the device limits are reverse voltage VR 75 V, peak reverse voltage VRM 100 V, and average forward current IF(AV) 200 mA at TA=25°C. |
| 2 | Anode | passive | Anode terminal (pin 2 in the datasheet pinout); the same device limits apply, including peak forward surge current IFSM 4 A for 0.001 ms. |
