MMSZ5228B-7-F

Diodes Incorporated · Zener Diodes · SOD-123

MMSZ5228B-7-F from Diodes Incorporated, 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 terminal, marked by the cathode band on the package; for MMSZ5228B it is the positive side in Zener breakdown, with nominal VZ 3.9V (3.71V to 4.10V) at IZT = 20mA.
2 A passive Anode terminal, the end opposite the cathode band; forward voltage is 0.9V at IF = 10mA.
