SMA2Z4.7A from XCH(旭昌辉), 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 of the SMA body with the marking band; it is positive with respect to the anode in zener (reverse) operation, with VZ 4.46 V min / 4.7 V nom / 4.94 V max at IZT = 106 mA. |
| 2 | A | passive | Anode, the lead at the unbanded end of the SMA body; forward voltage is 1.2 V at IF = 200 mA. |
