SZMM5Z5V1ST1G

onsemi · Zener Diodes · SOD-523

SZMM5Z5V1ST1G from onsemi, in a SOD-523. 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 (polarity band) of the Zener diode, which is the reverse Zener voltage terminal with VZ 4.98 V to 5.2 V at IZT = 5.0 mA for the 5V1 type.
2 Anode passive Anode of the Zener diode, with forward voltage VF of 0.9 V max at IF = 10 mA.
