IRF7821TR

UMW · MOSFETs · SOP-8

IRF7821TR from UMW, in a SOP-8. 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 S passive SOURCE terminal of the N-channel MOSFET (pins 1, 2 and 3 are internally common source).
2 S passive SOURCE terminal of the N-channel MOSFET (pins 1, 2 and 3 are internally common source).
3 S passive SOURCE terminal of the N-channel MOSFET (pins 1, 2 and 3 are internally common source).
4 G input GATE terminal that controls the MOSFET; the datasheet gives a VGS rating of ±20V (Gate-to-Source Voltage).
5 D passive DRAIN terminal of the N-channel MOSFET (pins 5 to 8 are internally common drain).
6 D passive DRAIN terminal of the N-channel MOSFET (pins 5 to 8 are internally common drain).
7 D passive DRAIN terminal of the N-channel MOSFET (pins 5 to 8 are internally common drain).
8 D passive DRAIN terminal of the N-channel MOSFET (pins 5 to 8 are internally common drain).

CAD (KiCad official)

  • Symbol: IRF7821TR
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOP-8 (KiCad packages3D, STEP)
  • 3D model files: irf7821tr-etched.step / irf7821tr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); irf7821tr.step / irf7821tr.glb are the bare package body.
