MMSZ4694T1G

onsemi · Zener Diodes · SOD-123

MMSZ4694T1G 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 by the polarity band on the package; the device regulates by reverse breakdown at its Zener voltage (VZ, 8.2 V nominal for MMSZ4694T1G).
2 Anode passive Anode terminal of the Zener diode; the datasheet specifies forward voltage VF = 0.9 V max at IF = 10 mA.
