SMA2Z4.3A
ZHIDE · Zener Diodes · SMA
SMA2Z4.3A 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; it goes positive relative to the anode in Zener breakdown (VZ 4.09 to 4.52 V at IZT 116 mA for SMA2Z4.3A). |
| 2 | A | passive | Anode, the end without the color band; the forward voltage is at most 1.2 V at IF 200 mA. |
