SMCJ8.0A-AT from Brightking, in a SMC(DO-214AB). 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 | K | passive | Cathode terminal, identified by the color band on the unidirectional SMCJ8.0A-AT (VRWM 8.0V, VBR 8.89~9.83V @1mA, VC 13.6V @110.3A). |
| 2 | A | passive | Anode terminal of the unidirectional SMCJ8.0A-AT; the datasheet gives no pin numbers, only that the color band marks the cathode. |
