Total gate charge at 10 V is 170 nC, and input capacitance at 50 V drain-source is 6860 pF. The gate charge figure sets the driver current needed for a target switching frequency: at 100 kHz, the average gate-drive current is 17 mA, well within the capability of a standard MOSFET driver IC. The maximum gate threshold voltage is 4 V at 150 µA drain current, and the recommended drive voltage for minimum Rds(on) is 10 V. A 10 V gate rail ensures the device is fully enhanced; driving with 5 V logic may leave the FET in the linear region at high current. ## Temperature range and package Junction temperature range is -55 °C to 175 °C, which qualifies the part for under-hood automotive and industrial enclosure environments where ambient temperatures can exceed 85 °C. The TO-220AB (TO-220-3 variant) package has a standard 0.100-inch pitch and a metal tab for screw or clip heatsink attachment. ## Lifecycle and compliance It is ROHS3 compliant, which means no exemptions for lead in solder or other restricted substances.","metaTitle":"IRFB4310ZPBF N-Channel MOSFET, 100V, 120A, TO-220-3","metaDescription":"IRFB4310ZPBF HEXFET N-Channel MOSFET, 100V Vdss, 120A Id, 6mOhm Rds(on) at 75A.
