SZMM5Z8V2ST1G

onsemi · Zener Diodes · SOD-523

SZMM5Z8V2ST1G 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; reverse Zener voltage VZ is 8.02 V min to 8.36 V max at IZT = 5.0 mA for the 8V2 device.
2 Anode passive Anode of the Zener diode; forward voltage VF is 0.9 V max at IF = 10 mA.
