MMBFJ270

onsemi · JFETs · SOT-23

MMBFJ270 from onsemi, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 G input Gate terminal with maximum gate-source voltage of ±30V and gate reverse leakage current not exceeding 200 pA at 20V.
2 S passive Source terminal, common reference point with maximum gate-source voltage of ±30V.
3 D passive Drain terminal with maximum drain-gate voltage of -30V and zero-gate-voltage drain current of -2.0 to -15 mA.

CAD (KiCad official)

  • Symbol: MMBFJ270
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: mmbfj270-etched.step / mmbfj270-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mmbfj270.step / mmbfj270.glb are the bare package body.
