BEP0640SC

BORN · Thyristor Surge Suppressors (TSS) · SMB

BEP0640SC 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 1 passive Bidirectional thyristor surge protector terminal with 58 V peak off-state voltage (5 µA max IDRM), 77 V max switching voltage at 800 mA, and 120 mA min holding current.
2 2 passive Bidirectional thyristor surge protector terminal interchangeable with pin 1, with 4 V max on-state voltage at 2.2 A and 80 pF max off-state capacitance.

CAD (KiCad official)

  • Symbol: BEP0640SC
  • Footprint: Diode_SMD:D_SMB
  • 3D model: SMB (KiCad packages3D, STEP)
  • 3D model files: bep0640sc-etched.step / bep0640sc-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bep0640sc.step / bep0640sc.glb are the bare package body.
