SZMMBZ27VCLT1G

onsemi · ESD And Surge Protection (TVS/ESD) · SOT-23

SZMMBZ27VCLT1G 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 first zener junction; the datasheet ties a unidirectional circuit between pins 1 and 3 (or 2 and 3).
2 ANODE passive Anode of the second zener junction; the datasheet ties a unidirectional circuit between pins 2 and 3 (or 1 and 3).
3 CATHODE passive Common cathode shared by both zener junctions, so the device protects two separate lines from one package.

CAD (KiCad official)

  • Symbol: SZMMBZ27VCLT1G
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: szmmbz27vclt1g-etched.step / szmmbz27vclt1g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); szmmbz27vclt1g.step / szmmbz27vclt1g.glb are the bare package body.
