TISP4350J3BJR-S

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

TISP4350J3BJR-S from BOURNS, in a SMB(DO-214AA). 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 R passive R (ring) terminal, the reference for all measurements, of the bidirectional protector, which stands off VDRM of ±275 V and limits to a breakover voltage V(BO) of ±350 V for the TISP4350J3BJ.
2 T passive T (tip) terminal of the bidirectional protector, which stands off VDRM of ±275 V and limits to a breakover voltage V(BO) of ±350 V for the TISP4350J3BJ, with a holding current of at least ±150 mA.
