SMCJ8.0CA-L 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 | Terminal 1 (cathode on the unipolar symbol); on the bipolar SMCJ8.0CA-L it is interchangeable with pin 2, with 8 V reverse stand-off, 8.89-9.83 V breakdown at 1 mA and 13.6 V max clamping at 44.2 A. |
| 2 | Anode | passive | Terminal 2 (anode on the unipolar symbol); on the bipolar SMCJ8.0CA-L it is interchangeable with pin 1, with 8 V reverse stand-off, 8.89-9.83 V breakdown at 1 mA and 13.6 V max clamping at 44.2 A. |
