MMSZ4690

Changjing · Zener Diodes · SOD-123

MMSZ4690 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 banded end of the SOD-123 body, marked "−" on the page 3 outline, which goes positive in zener reverse breakdown.
2 A passive Anode, the unbanded end of the SOD-123 body, marked "+" on the page 3 outline, which is the forward-conduction terminal (VF 0.9 V at IF = 10 mA).
