IRL520NSTRLPBF

Infineon Technologies · MOSFETs · D2PAK

IRL520NSTRLPBF from Infineon Technologies, in a D2PAK. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 G input Gate. Logic-level MOSFET control input; VGS(th) = 1.0-2.0 V, absolute max VGS = ±16 V. Drives the N-channel HEXFET on/off with respect to the Source.
2 D passive Drain. High-voltage power terminal (VDSS = 100 V, ID = 10 A at TC = 25 °C, RDS(on) = 0.18 Ω at VGS = 10 V). Internally connected to the metal mounting tab of the D²Pak.
3 S passive Source. Low-side power terminal of the N-channel MOSFET; return for the load current and reference for VGS. Body-diode anode is on Source (integral p-n junction diode: VSD ≈ 1.3 V, IS = 10 A).
TAB D passive Mounting tab, electrically connected to the Drain. Primary thermal path (RθJC = 3.1 °C/W); solder to a copper pad for heatsinking in surface-mount applications.
