SMAJ54CA from Shandong Jingdao Microelectronics, in a SMA. 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 | Pin 1 is labelled Cathode in the datasheet PINNING table, which is given for the unipolar symbol; the datasheet states no voltage or current limits for this pin individually, only the device ratings of 400 W peak pulse power and -65 to +150 °C operating junction and storage temperature. |
| 2 | Anode | passive | Pin 2 is labelled Anode in the datasheet PINNING table, which is given for the unipolar symbol; the datasheet states no voltage or current limits for this pin individually, only the device ratings of 400 W peak pulse power and -65 to +150 °C operating junction and storage temperature. |
