IRLMS1503TRPBF

Infineon Technologies · MOSFETs · SOT-23-6

IRLMS1503TRPBF from Infineon Technologies, in a SOT-23-6. 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 D passive Drain, internally connected to the other drain pins (2, 5, 6); drain-to-source breakdown is 30V min and continuous drain current is 3.2A at TA=25°C.
2 D passive Drain, internally connected to the other drain pins (1, 5, 6); drain-to-source breakdown is 30V min and continuous drain current is 3.2A at TA=25°C.
3 G input Gate of the N-channel MOSFET; gate-to-source voltage is rated ±20V max and threshold voltage is 1.0V min.
4 S passive Source of the N-channel MOSFET; body diode continuous source current is 1.7A max.
5 D passive Drain, internally connected to the other drain pins (1, 2, 6); RDS(on) is 0.100 ohm max at VGS=10V, ID=2.2A.
6 D passive Drain, internally connected to the other drain pins (1, 2, 5); RDS(on) is 0.100 ohm max at VGS=10V, ID=2.2A.
