BEP4200TB

BORN · Semiconductor Discharge Tubes (TSS) · SMA

BEP4200TB from BORN, in a SMA. 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 Bidirectional thyristor surge suppressor terminal (symbol shows two symmetric terminals); device is rated VDRM 400 V (VD), 550 V max VS, 4000 V 10/700us peak pulse voltage.
2 T2 passive Bidirectional thyristor surge suppressor terminal on the opposite end of the SMA body; the outline drawing marks a cathode band at one end, and peak pulse current is 80 A (10/1000us) and 250 A (8/20us).

CAD (KiCad official)

  • Symbol: BEP4200TB
  • Footprint: Diode_SMD:D_SMA
  • 3D model: SMA (KiCad packages3D, STEP)
  • 3D model files: bep4200tb-etched.step / bep4200tb-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bep4200tb.step / bep4200tb.glb are the bare package body.
