1SMA4760A SMA 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 of the zener diode, the end carrying the marking band in the package picture; total power dissipation is max. 1 W at Tc=75°C and the zener voltage range for the series is 3.3V to 330V. |
| 2 | A | passive | Anode of the zener diode; forward voltage is 1.2 V at IF = 200 mA and junction and storage temperature range is -55 to +150 °C. |
