MMBZ27VCL

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

MMBZ27VCL from Nexperia, 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 A1 passive Anode of diode 1, one of the two unidirectional ESD protection diodes that share common cathode pin 3; the datasheet gives no separate electrical limit for this pin.
2 A2 passive Anode of diode 2, one of the two unidirectional ESD protection diodes that share common cathode pin 3; the datasheet gives no separate electrical limit for this pin.
3 CC passive Common cathode shared by both ESD protection diodes; the datasheet measures peak pulse power and clamping voltage from pin 1 or 2 to pin 3, and gives its soldering point for thermal resistance.

  • Symbol: MMBZ27VCL
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: mmbz27vcl-etched.step / mmbz27vcl-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mmbz27vcl.step / mmbz27vcl.glb are the bare package body.

Provenance

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