SMAJ6.8CA from UMW, 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 | A1 | passive | Bi-directional TVS terminal 1; the part is unmarked and symmetric, so either terminal can connect to the protected line (5.80 V stand-off, 6.45-7.14 V breakdown at 10 mA, 10.5 V max clamping at 38.1 A). |
| 2 | A2 | passive | Bi-directional TVS terminal 2; the part is unmarked and symmetric, so either terminal can connect to the return or ground side (400 W peak pulse power, 10/1000 μs). |
