40 V, 70 A N-channel — the conduction-loss floor
The 42 nC total gate charge at 10 V tells the drive circuit how much current is needed to switch the FET at the target frequency.
175°C junction — thermal budget for tight environments
That 175°C ceiling suits automotive under-hood and industrial power-conversion designs where the thermal headroom is tight. The 79 W maximum power dissipation at case temperature assumes the tab is soldered to a sufficient copper area on the board — the D²Pak package (PG-TO-263-3-2) relies on that exposed tab for heat extraction.
Active production — no LTB watch needed
The series is ROHS3 compliant.
