Shikues · Zener Diodes · SMA
1SMA4753AG 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 terminal of the zener diode (pin 1 per datasheet pinning table); the device is a 1 W silicon planar zener with a 3.3V to 330V zener voltage range. |
| 2 | Anode | passive | Anode terminal of the zener diode (pin 2 per datasheet pinning table); forward voltage is 1.2 V max at IF = 200 mA. |
