1N4148W-AU

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.

CAD (KiCad official)

  • Symbol: 1N4148W-AU
  • Footprint: Diode_SMD:D_SOD-123F
  • 3D model: SOD-123 (KiCad packages3D, STEP)
  • 3D model files: 1n4148w-au-etched.step / 1n4148w-au-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); 1n4148w-au.step / 1n4148w-au.glb are the bare package body.
