SZMM3Z15VT1G

onsemi · Zener Diodes · SOD-323

SZMM3Z15VT1G from onsemi, in a SOD-323. 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 of the Zener diode, indicated by the polarity band; the 15 V part (device marking 0T) regulates at VZ 14.3 V min, 15 V nom, 15.8 V max at IZT = 5 mA.
2 Anode passive Anode of the Zener diode (SOD-323 CASE 477 Style 1, pin 2), with forward voltage VF = 0.9 V max at IF = 10 mA.
