1SMA4756AG from Shikues, in a 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 of the zener diode (pin 1 per the pinning table); the zener reverse voltage range for the series is 3.3V to 330V with 1 W max power dissipation. |
| 2 | Anode | passive | Anode of the zener diode (pin 2 per the pinning table); forward voltage is 1.2 V max at IF = 200 mA. |
