MMBZ5248BLT1G

onsemi · Zener Diodes · SOT-23

MMBZ5248BLT1G 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 terminal of the Zener diode; the datasheet gives forward voltage VF = 0.9 V max at IF = 10 mA for all types.
2 NC unconnected No connection; the datasheet specifies this pin as not connected internally.
3 Cathode passive Cathode terminal of the Zener diode, marked by the polarity band on the package, used as the regulated output in reverse-bias operation.

CAD (KiCad official)

  • Symbol: MMBZ5248BLT1G
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: mmbz5248blt1g-etched.step / mmbz5248blt1g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mmbz5248blt1g.step / mmbz5248blt1g.glb are the bare package body.
