AUIRFS4127TRL

Infineon Technologies · MOSFETs · D2PAK

AUIRFS4127TRL from Infineon Technologies, in a D2PAK. 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; controls the channel, with VGS rated ±20 V and a gate threshold of 3.0 V min to 5.0 V max at ID = 250µA.
2 D passive Drain; also connected to the tab, with VDSS of 200 V and continuous drain current of 72 A at TC = 25°C.
3 S passive Source; current return path with continuous body-diode source current of 72 A and pulsed 300 A.

CAD (KiCad official)

  • Symbol: AUIRFS4127TRL
  • Footprint: Package_TO_SOT_SMD:TO-263-2
  • 3D model: D2PAK (KiCad packages3D, STEP)
  • 3D model files: auirfs4127trl-etched.step / auirfs4127trl-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); auirfs4127trl.step / auirfs4127trl.glb are the bare package body.
