SMAJ15CAT from Agertech, 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 | Cathode terminal of the SMA outline, listed as pin 1 in the PINNING table; the datasheet gives no separate voltage or current limit for this pin. |
| 2 | Anode | passive | Anode terminal of the SMA outline, listed as pin 2 in the PINNING table; the datasheet gives no separate voltage or current limit for this pin. |
