SMA4762A

Yangzhou Yangjie Elec Tech · Zener Diodes · DO-214AC(SMA)

SMA4762A from Yangzhou Yangjie Elec Tech, in a DO-214AC(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, marked by the cathode line on the package; the Zener (SMA4762A: 82 V typ. at IZT = 3.0 mA) is reverse-biased with this pin positive relative to the anode.
2 A passive Anode terminal of the Zener diode, the end opposite the cathode line; maximum forward voltage 1.2 V at IF = 200 mA.
