It delivers a continuous drain current of 120 A at 25 °C case temperature with a 75 V drain-source breakdown, all in a through-hole TO-247AC package. That 3.3 mOhm is the worst-case ceiling at 25 °C junction — expect it to climb with temperature per the normalized curve. Gate drive requirement is explicit: the 4 V maximum threshold at 250 µA means a 10 V gate signal is needed to fully enhance the channel. ## Switching loss and driver budget Total gate charge is 220 nC at 10 V. Input capacitance Ciss is 9400 pF at 50 V Vds. ## Thermal design: the TO-247 tab matters Maximum power dissipation is 340 W at case temperature 25 °C. That number is only achievable with the TO-247AC tab bolted to an infinite heatsink — real-world designs derate from that ceiling. The junction-to-case thermal path is through the metal tab; a thermal pad or grease plus a screw mount is mandatory for any load above a few tens of watts. The 175 °C ceiling suits under-hood automotive, industrial motor drives, and high-ambient enclosures. Packaging is tube (the TO-247 leads are too large for tape-and-reel).","metaTitle":"IRFP3077PBF HEXFET N-Channel MOSFET, 75V 120A TO-247","metaDescription":"IRFP3077PBF HEXFET N-Channel MOSFET from Infineon: 75V Vdss, 120A Id, 3.3mOhm Rds(on) at 10V.
