8.0SMDJ54A

Littelfuse · TVS · DO-214AB(SMCJ)

8.0SMDJ54A from Littelfuse, in a DO-214AB(SMCJ). 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 Cathode passive Cathode terminal of the unidirectional TVS, marked by the color band and the positive end, with VR 54 V, VBR 60.0-66.3 V at 1 mA and VC 87.1 V at 92.0 A (10/1000μs).
2 Anode passive Anode terminal of the unidirectional TVS, opposite the cathode band, with 8000 W peak pulse power at 10/1000μs.
