The gate charge totals 72 nC at 10 V, which determines the drive current needed to hit a given switching frequency. ## 175 °C junction — where this part lives That 175 °C ceiling matters for designs where the MOSFET sits near a hot heatsink or inside a sealed enclosure — engine ECUs, industrial power stages, or downhole instrumentation. The maximum power dissipation is 107 W at the case, derated to 3.8 W in still air at 25 °C ambient, so the thermal path through the D2PAK tab to a copper plane or heatsink is what actually unlocks the current rating. ## D2PAK footprint and sourcing posture ROHS3 compliant.","metaTitle":"IRFZ46NSTRLPBF N-Channel MOSFET, 55 V, 53 A, D2PAK","metaDescription":"IRFZ46NSTRLPBF N-channel MOSFET, 55 V drain-source, 53 A continuous drain, 16.5 mOhm Rds(on) at 10 V.
