SMAJ7.5CA 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 PINNING table for the SMA package; the datasheet gives no further electrical limit for this pin. |
| 2 | Anode | passive | Pin 2 is labelled Anode in the PINNING table for the SMA package; the datasheet gives no further electrical limit for this pin. |
