SMDJ100CA 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 in the unipolar symbol); for SMDJ100CA bidirectional it has 100 V stand-off, 111-123 V breakdown at 1 mA and 162 V max clamping at 18.5 A peak pulse current. |
| 2 | Anode | passive | Terminal 2 (anode in the unipolar symbol); for SMDJ100CA bidirectional it has 100 V stand-off, 111-123 V breakdown at 1 mA and 162 V max clamping at 18.5 A peak pulse current. |
