US5MB

Shandong Jingdao Microelectronics · Diodes - Fast Recovery Rectifiers · SMB

US5MB from Shandong Jingdao Microelectronics, in a SMB. 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 rectifier diode (pin 1 per pinning table); blocks up to 1000 V DC reverse voltage for US5MB.
2 Anode passive Anode terminal of the rectifier diode (pin 2 per pinning table); carries up to 5 A maximum average forward current.

CAD (KiCad official)

  • Symbol: US5MB
  • Footprint: Diode_SMD:D_SMB
  • 3D model: SMB (KiCad packages3D, STEP)
  • 3D model files: us5mb-etched.step / us5mb-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); us5mb.step / us5mb.glb are the bare package body.
