MMBZ27VAL-7-F

Diodes Incorporated · TVS · SOT-23

MMBZ27VAL-7-F from Diodes Incorporated, 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 K1 passive Cathode of TVS diode 1 (unidirectional), which clamps to a maximum of 40V at 1.0A and has a 22V reverse working voltage for the MMBZ27VAL.
2 K2 passive Cathode of TVS diode 2 (unidirectional), which clamps to a maximum of 40V at 1.0A and has a 22V reverse working voltage for the MMBZ27VAL.
3 A passive Common anode of both TVS diodes, normally tied to ground or the return reference; forward voltage is 0.9V max at 10mA.

CAD (KiCad official)

  • Symbol: MMBZ27VAL-7-F
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: mmbz27val-7-f-etched.step / mmbz27val-7-f-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mmbz27val-7-f.step / mmbz27val-7-f.glb are the bare package body.
