MMBF170

TECH PUBLIC · MOSFETs · SOT-23

MMBF170 from TECH PUBLIC, 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 G input Gate; gate-source voltage limited to ±20 V absolute maximum, with VGS(th) of 1 V min and 1.6 V typ at ID=250 µA.
2 S passive Source; the MOSFET source terminal, with continuous drain current of 0.3 A at TA=25°C and body diode forward current up to 0.3 A.
3 D passive Drain; drain-source voltage rated 60 V maximum, with continuous drain current of 0.3 A at TA=25°C and pulsed 1.5 A.

CAD (KiCad official)

  • Symbol: MMBF170
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: mmbf170-etched.step / mmbf170-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mmbf170.step / mmbf170.glb are the bare package body.

Provenance

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