The 44 nC figure also means the driver's peak current rating should be checked against the rise-time target; a 2 A driver will switch the gate in roughly 22 ns, ignoring layout inductance. ## Thermal and temperature range Maximum power dissipation is 110 W at the case — the actual usable power depends on the PCB copper area and airflow. The 175 °C Tj max provides headroom for high-ambient designs, but the RthJA from the DPAK package to ambient will be the limiting factor in a real layout.","metaTitle":"IRFR2905ZTRPBF N-Channel MOSFET, 55 V, 42 A, 14.5 mOhm DPAK","metaDescription":"IRFR2905ZTRPBF HEXFET N-channel MOSFET, 55 V drain-source, 42 A continuous, 14.5 mOhm Rds(on) at 10 V.
