On-resistance and conduction loss
The IRFS3006TRL7PP: Maximum on-resistance is 2.1 mOhm at 168 A drain current with a 10 V gate drive.
Switching characteristics and gate drive
Gate charge is 300 nC at 10 V. Input capacitance is 8850 pF at 50 V drain-to-source. The ±20 V maximum gate-to-source voltage gives good margin for gate-drive overshoot.
The TO-263-7 D²Pak (also called D2PAK-7) is a surface-mount power package with a large exposed copper tab for thermal conduction to the PCB. The seven leads include an extra source connection that lowers the package resistance and improves current sharing versus the standard 3-lead D²Pak. The supplier device package is D2PAK (7-Lead). Mounting requires a copper land pattern with adequate thermal vias to a heatsink layer; the tab is the drain connection and must be isolated or connected accordingly.
The HEXFET® series is an established Infineon power MOSFET family with broad application support and multiple second-source options in similar voltage/current classes.
