SMAJ100A-AT from Brightking Elec (TAIWAN), 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 terminal of the unidirectional TVS, marked by the color band, connected to the protected line (VRWM 100 V, VBR 111-123 V at 1 mA, VC max 162 V at 2.5 A IPP). |
| 2 | A | passive | Anode terminal of the unidirectional TVS, opposite the cathode band, normally connected to ground/return. |
