SMAJ6.5A-TP from MCC(Micro Commercial Components), 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 | Cathode | passive | Cathode terminal, the marked end of the unidirectional SMAJ6.5A TVS, which carries the 400 W peak pulse power rating (10/1000 µs) with a 6.5 V reverse standoff voltage (VRWM). |
| 2 | Anode | passive | Anode terminal of the unidirectional SMAJ6.5A TVS, which clamps transients to a maximum clamping voltage of 11.2 V at 35.7 A IPP per the electrical characteristics table. |
