BEP3100SB

BORN · Thyristor Surge Suppressors (TSS) · SMB

BEP3100SB from BORN, 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 T1 passive First terminal of the bidirectional thyristor surge suppressor, at the end of the SMB body marked with the cathode band, with off-state voltage VD of 275 V and switching voltage VS of 350 V max for BEP3100SB.
2 T2 passive Second terminal of the bidirectional thyristor surge suppressor, at the end of the SMB body opposite the cathode band, with off-state voltage VD of 275 V and switching voltage VS of 350 V max for BEP3100SB.

CAD (KiCad official)

  • Symbol: BEP3100SB
  • Footprint: Diode_SMD:D_SMB
  • 3D model: SMB (KiCad packages3D, STEP)
  • 3D model files: bep3100sb-etched.step / bep3100sb-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bep3100sb.step / bep3100sb.glb are the bare package body.
