That is a heavy load for a standard gate driver — a 1 A driver switching at 100 kHz needs 25 mA average drive current, but the peak current during the Miller plateau determines the switching time. The 7670 pF input capacitance at 50 V confirms this is a large-die device; plan for a dedicated driver stage, not a logic-output pin. ## Through-hole package and thermal path The TO-220-3 (TO-220AB) package is a through-hole mount with a metal tab for heatsink attachment. The 300 W power dissipation rating assumes the tab is bolted to an infinite heatsink — real-world dissipation is limited by the thermal interface and airflow. The -55°C to 175°C junction range covers military-temperature applications; the 4 V threshold at 250 µA is a standard logic-level turn-on, but the drive voltage for minimum Rds(on) is 10 V. ## Lifecycle and compliance The ±20 V maximum gate-source rating gives margin for gate-drive overshoot in noisy environments.","metaTitle":"IRFB4310PBF HEXFET N-Ch MOSFET, 100V 130A TO-220AB","metaDescription":"IRFB4310PBF N-channel HEXFET MOSFET: 100V Vdss, 130A Id, 7mOhm Rds(on) at 75A.
