SMBJ5.0A

MDD Microdiode Semiconductor · ESD And Surge Protection (TVS/ESD) · DO-214AA(SMB)

SMBJ5.0A from MDD Microdiode Semiconductor, in a DO-214AA(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 K passive Cathode terminal, marked by the cathode band on the body (unidirectional SMBJ5.0A); stand-off voltage VRWM 5.0 V, breakdown 6.40~7.00 V at 10 mA, max clamping 9.2 V at 65.3 A.
2 A passive Anode terminal, the end opposite the cathode band; 600 W peak pulse power at 10/1000μs and operating junction/storage range -65 to +150 ℃.

  • Symbol: SMBJ5.0A
  • Footprint: Diode_SMD:D_SMB
  • 3D model: DO-214AA(SMB) (KiCad packages3D, STEP)
  • 3D model files: smbj5-0a-etched.step / smbj5-0a-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); smbj5-0a.step / smbj5-0a.glb are the bare package body.
