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. |
