BEP0300SC

BORN · Thyristor Surge Suppressors (TSS) · DO-214AA(SMB)

BEP0300SC from BORN, 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 SMB body; BEP0300SC has VDRM 25 V, VS 40 V max, and IPP 100 A (10/1000us) per the ratings table.
2 A passive Anode terminal at the opposite end of the SMB body from the cathode band; ITSM 30 A (60 Hz) and IPK 400 A (8/20us) per the ratings table.

CAD (KiCad official)

  • Symbol: BEP0300SC
  • Footprint: Diode_SMD:D_SMB
  • 3D model: DO-214AA(SMB) (KiCad packages3D, STEP)
  • 3D model files: bep0300sc-etched.step / bep0300sc-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bep0300sc.step / bep0300sc.glb are the bare package body.
