IRFML8244TR

UMW · MOSFETs · SOT-23

IRFML8244TR from UMW, 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 G input Gate terminal of the MOSFET, with gate-to-source voltage rated at ±20 V (VGS) in the maximum ratings.
2 S passive Source terminal of the MOSFET, the reference for VGS, with continuous source (body diode) current IS rated at 1.25 A.
3 D passive Drain terminal of the MOSFET, rated for VDS of 25 V and continuous drain current ID of 5.8 A at TA=25°C.
