1.5SMC82A 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 on the package; 1.5SMC82A has VR 70.1 V, VBR 77.9-86.1 V at 1 mA and VC 113 V at 13.5 A Ipp. |
| 2 | Anode | passive | Anode terminal of the unidirectional TVS, opposite the cathode band end; 1500 W peak pulse power at 10/1000µs. |
