SZMM5Z4688T1G

onsemi · Zener Diodes · SOD-523

SZMM5Z4688T1G 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, marked by the polarity band on the package (Style 1 outline, pin 1 = cathode); the Zener regulating terminal of the MM5Z4688 (nominal VZ 4.7 V, IZT 50 µA, max IR 10 µA at VR 3 V per the electrical table).
2 Anode passive Anode, the terminal opposite the cathode band (Style 1 outline, pin 2 = anode); the datasheet gives no separate pin-level limits for this terminal.

CAD (KiCad official)

  • Symbol: SZMM5Z4688T1G
  • Footprint: Diode_SMD:D_SOD-523
  • 3D model: SOD-523 (KiCad packages3D, STEP)
  • 3D model files: szmm5z4688t1g-etched.step / szmm5z4688t1g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); szmm5z4688t1g.step / szmm5z4688t1g.glb are the bare package body.
