SMCJ14CA from Shandong Jingdao Microelectronics, in a SMC. 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 | The PINNING table labels pin 1 as Cathode for the unipolar device, but the bipolar (CA) symbol is drawn without polarity, so the datasheet does not assign a distinct role to this pin for SMCJ14CA. |
| 2 | Anode | passive | The PINNING table labels pin 2 as Anode for the unipolar device, but the bipolar (CA) symbol is drawn without polarity, so the datasheet does not assign a distinct role to this pin for SMCJ14CA. |
