MMSZ5236B

hongjiacheng · Zener Diodes · SOD-123

MMSZ5236B from hongjiacheng, 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 marked by the cathode band; the Zener voltage VZ is 7.13 V min, 7.5 V nom and 7.88 V max at IZT=20 mA for the MMSZ5236B.
2 A passive Anode, the end opposite the cathode band; forward voltage is 0.9 V at IF=10 mA and power dissipation is 500 mW.
