TISP4040L1AJR-S

BOURNS · Thyristor Surge Suppressors (TSS) · DO-214AC(SMA)

TISP4040L1AJR-S from BOURNS, in a DO-214AC(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 R passive Terminal R (alternative line designator B) of the symmetrical bidirectional thyristor, with VDRM of ±25 V and V(BO) of ±40 V for the '4040; the device is symmetrical and terminal 1 is not marked on the part.
2 T passive Terminal T (alternative line designator A) of the symmetrical bidirectional thyristor, with VDRM of ±25 V and V(BO) of ±40 V for the '4040; the device is symmetrical so polarity does not matter.
