BEP0080SB

BORN · Thyristor Surge Suppressors (TSS) · SMB

BEP0080SB 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 Terminal 1 of the bidirectional thyristor surge suppressor (symmetric, no polarity); off-state voltage VD 6 V, switching voltage VS 25 V max at 100 kV/s, holding current IH 40 mA min.
2 T2 passive Terminal 2 of the bidirectional thyristor surge suppressor (symmetric, no polarity); peak pulse current 80 A (10/1000us) and 250 A (8/20us), on-state voltage 4 V max at 2.2 A.
