MMBZ5226BLT1G

onsemi · Zener Diodes · SOT-23

MMBZ5226BLT1G from onsemi, in a SOT-23. 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 Anode passive Anode of the Zener diode; the datasheet gives forward voltage VF of 0.95 V max at IF = 10 mA for this series, with the cathode marked by the polarity band on the package.
2 NC unconnected No connection per the Style 8 pinout, so this pin is not connected internally and is not used in the circuit.
3 Cathode passive Cathode of the Zener diode, identified by the polarity band; for the MMBZ5226BLT1G the nominal Zener voltage VZ is 3.3 V (3.13 V min to 3.47 V max) at IZT = 20 mA.

  • Symbol: MMBZ5226BLT1G
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: mmbz5226blt1g-etched.step / mmbz5226blt1g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mmbz5226blt1g.step / mmbz5226blt1g.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:
