SMAJ6.0AJ from WeEn Semiconductors, 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 of the uni-directional TVS (cathode band side), connected to the protected line, which clamps at VC max 10.3 V at Ipp 38.8 A with VR 6 V and VBR 6.8-7.32 V. |
| 2 | A | passive | Anode of the uni-directional TVS, normally connected to ground or return, and forward-conducting with VF 3.5 V at IF = 35 A. |
