SMAJ17AQ-13-F from Diodes Incorporated, 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 | K | passive | Cathode terminal, marked by the cathode band on the uni-directional SMAJ17AQ (VRWM 17V, VBR 18.9V to 20.9V, VC 27.6V at IPP 14.5A). |
| 2 | A | passive | Anode terminal at the end opposite the cathode band; the 400W peak pulse power TVS clamps surges between the anode and cathode. |
