MMSZ4711T1G

onsemi · Zener Diodes · SOD-123

MMSZ4711T1G from onsemi, 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 Cathode passive Cathode terminal of the Zener diode, identified on the package by the polarity band (SOD-123 Style 1: pin 1 = Cathode).
2 Anode passive Anode terminal of the Zener diode, opposite the cathode (polarity band) side (SOD-123 Style 1: pin 2 = Anode).
