SML4758A-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 | K | passive | Cathode, the terminal marked by the cathode band; it goes positive relative to the anode in Zener regulation, and the SML4758A has a nominal VZ of 56 V at IZT1 = 4.5 mA. |
| 2 | A | passive | Anode, the terminal opposite the cathode band; the maximum power dissipation is 1000 mW at TL = 75 °C. |
