MMSZ4700

Changjing · Zener Diodes · SOD-123

MMSZ4700 from Changjing, in a SOD-123. 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 with the black band on the SOD-123 outline, marked "−" in the package drawing; the zener reverse voltage VZ is specified at IZT with this pin positive.
2 A passive Anode, the end opposite the cathode band, marked "+" in the package drawing; forward voltage VF is 0.9 V at IF = 10 mA.
