SZMMSZ4702T1G

onsemi · Zener Diodes · SOD-123

SZMMSZ4702T1G 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, indicated by the polarity band; the Zener (reverse) voltage is 15 V nominal (14.25 V min to 15.75 V max) at IZT = 50 µA for this device.
2 Anode passive Anode terminal of the Zener diode; forward voltage is 0.9 V max at IF = 10 mA.

CAD (KiCad official)

  • Symbol: SZMMSZ4702T1G
  • Footprint: Diode_SMD:D_SOD-123F
  • 3D model: SOD-123 (KiCad packages3D, STEP)
  • 3D model files: szmmsz4702t1g-etched.step / szmmsz4702t1g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); szmmsz4702t1g.step / szmmsz4702t1g.glb are the bare package body.
