ZHIDE · Zener Diodes · SMA
SMA3Z5.1A from ZHIDE, 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 | K | passive | Cathode, the end marked by the color band; the Zener diode is reverse-biased here for regulation (VZ 5.1 V nominal, 4.85-5.36 V, at IZT 147 mA). |
| 2 | A | passive | Anode terminal of the Zener diode; maximum forward voltage is 1.2 V at 200 mA. |
