TDM3428B

Techcode Semicon · MOSFETs · TO-252

TDM3428B from Techcode Semicon, in a TO-252. 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 terminal of the N-channel MOSFET, with a gate-source voltage limit of ±20 V and a gate threshold of 1.4 V min to 2.5 V max at 250 μA.
2 D passive Drain terminal, also the exposed tab, with a drain-source voltage rating of 30 V and a continuous drain current of 45 A at TC=25℃ (limited by bonding wire).
3 S passive Source terminal of the N-channel MOSFET, with a diode continuous forward current of 5 A at TC=25℃.

CAD (KiCad official)

  • Symbol: TDM3428B
  • Footprint: Package_TO_SOT_SMD:TO-252-2
  • 3D model: TO-252 (KiCad packages3D, STEP)
  • 3D model files: tdm3428b-etched.step / tdm3428b-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tdm3428b.step / tdm3428b.glb are the bare package body.
