TF3402

TF · MOSFETs · SOT-23

TF3402 from TF, 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 GATE input Gate terminal of the N-channel MOSFET; gate-source voltage is rated to ±12 V (absolute maximum).
2 SOURCE passive Source terminal of the N-channel MOSFET and the reference for gate-source and drain-source voltages.
3 DRAIN passive Drain terminal of the N-channel MOSFET; drain-source voltage is rated to 30 V with continuous drain current of 4 A at TA=25°C.

CAD (KiCad official)

  • Symbol: TF3402
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: tf3402-etched.step / tf3402-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tf3402.step / tf3402.glb are the bare package body.
