SMAJ11A-E3 from Vishay Intertech, 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 of the uni-directional SMAJ11A (marked by the cathode band); connect to the protected positive line, with VWM 11 V and VBR 12.2 V to 13.5 V at 1.0 mA. |
| 2 | A | passive | Anode terminal of the uni-directional SMAJ11A, normally connected to ground or the return line; the clamping voltage is 18.2 V max at IPPM of 22.0 A. |
