SMAJ6V8A from YFW, 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 | Cathode | passive | Cathode terminal (pin 1) of the unipolar SMAJ6V8A; the datasheet gives device limits of 400 W peak pulse power and -55 to +150 °C junction and storage temperature, with no pin-specific limit. |
| 2 | Anode | passive | Anode terminal (pin 2) of the unipolar SMAJ6V8A; the datasheet gives no pin-specific limit beyond the device ratings. |
