IRLR7843TR

UMW · MOSFETs · TO-252

IRLR7843TR from UMW, 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; the datasheet's absolute maximum gate-to-source voltage is VGS = ±20 V.
2 D passive DRAIN terminal; the datasheet's absolute maximum drain-source voltage is VDS = 30 V, with continuous drain current ID = 161 A at TC = 25°C (VGS = 10 V).
3 S passive SOURCE terminal; the reference terminal for VGS and VDS, with the maximum drain-source voltage of 30 V given in the absolute maximum ratings.

CAD (KiCad official)

  • Symbol: IRLR7843TR
  • Footprint: Package_TO_SOT_SMD:TO-252-2
  • 3D model: TO-252 (KiCad packages3D, STEP)
  • 3D model files: irlr7843tr-etched.step / irlr7843tr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); irlr7843tr.step / irlr7843tr.glb are the bare package body.
