YFW · TVS · DO-214AC(SMA)
SMAJ6V8CA 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 | Terminal labelled Cathode in the package pinning (1.Cathode, 2.Anode); the datasheet's ratings for this device apply across the two terminals, with peak pulse power 400 W, reverse stand-off voltage 5.8 V and clamp voltage 10.5 V at 39 A for the SMAJ6V8CA. |
| 2 | Anode | passive | Terminal labelled Anode in the package pinning (1.Cathode, 2.Anode); the datasheet's ratings for this device apply across the two terminals, with operating junction and storage temperature range of -55 to +150 °C. |
