The IRL530NSTRLPBF: The junction temperature range is -55°C to 175°C.
Gate drive and switching — sizing the driver for the 34 nC gate charge
Gate charge is 34 nC at 5 V. Drive voltage range for rated Rds(on) is 4 V to 10 V. Input capacitance is 800 pF at 25 V.
Package and thermal — the D2PAK tab is the drain
The IRL530NSTRLPBF comes in a D2PAK (TO-263-3) surface-mount package. The datasheet specifies 79 W power dissipation at the case — that figure assumes the tab is held at 25 °C, which requires a substantial copper area or a heatsink on the back side of the board.
