SMAJ70A-E3 from Vishay Intertech, 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 | Cathode | passive | Cathode terminal at the cathode-band end of the unidirectional SMAJ70A, which has a 70 V stand-off voltage (VWM) and 77.8 V to 86.0 V breakdown voltage (VBR) at 1.0 mA. |
| 2 | Anode | passive | Anode terminal at the end opposite the cathode band, with a 400 W peak pulse power rating (10/1000 μs) and a maximum clamping voltage of 113 V at 3.5 A. |
