US1BW

Shandong Jingdao Microelectronics · Fast Recovery / High Efficiency Diodes · SOD-123FL

US1BW from Shandong Jingdao Microelectronics, in a SOD-123FL. 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 US1BW ultrafast recovery rectifier, per the PINNING table; the datasheet gives no pin-specific electrical limits.
2 Anode passive Anode terminal of the US1BW ultrafast recovery rectifier, per the PINNING table; the datasheet gives no pin-specific electrical limits.

CAD (KiCad official)

  • Symbol: US1BW
  • Footprint: Diode_SMD:D_SOD-123F
  • 3D model: SOD-123FL (KiCad packages3D, STEP)
  • 3D model files: us1bw-etched.step / us1bw-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); us1bw.step / us1bw.glb are the bare package body.
