SMCJ12A-E3 from Vishay Intertech, 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, the end marked with the cathode band on this uni-directional SMCJ12A (VWM 12 V, VBR 13.3 V to 14.7 V at 1.0 mA, VC 19.9 V at IPPM 75.4 A). |
| 2 | A | passive | Anode terminal, the unbanded end of the uni-directional SMCJ12A; the 1500 W (10/1000 µs) device is connected reverse-biased so the cathode sits at the more positive potential. |
