SMAJ15A from hongjiacheng, in a DO-214AC(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 | K | passive | Cathode of the unidirectional SMAJ15A, identified by the cathode band on the package, connected to the protected line (VRWM 15 V, VBR 16.7 to 18.5 V at 1 mA, VC 24.4 V at IPP 16.4 A). |
| 2 | A | passive | Anode of the unidirectional SMAJ15A, the terminal opposite the cathode band, usually connected to ground (400 W peak pulse power at 10/1000µs). |
