SMAJ6.5A-AT from Brightking Elec (TAIWAN), in a SMA(DO-214AC). 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, marked by the color band on the unidirectional SMAJ6.5A-AT (VRWM 6.5V, VBR 7.22~7.98V at 10mA, VC 11.2V at 35.7A IPP). |
| 2 | A | passive | Anode, the terminal opposite the cathode band on the unidirectional SMAJ6.5A-AT, which handles 400W peak pulse power at 10/1000μs. |
