The IRFR2607ZTRPBF: Gate charge totals 51 nC at 10 V, so a gate driver sourcing 1 A switches the FET in roughly 50 ns. Input capacitance is 1440 pF at 25 V Vds — moderate for a 42 A device, meaning the switching losses stay manageable up to a few hundred kHz in a typical buck or boost converter.
Package and thermal path in the DPAK
The 42 A rating assumes the case is held at 25 °C — in a real board with limited copper, derate the current per the datasheet's thermal impedance curve.
Active production and sourcing posture
ROHS3 compliant.
