For a hard-switched converter at 100 kHz, the average gate-drive current is 3 mA — well within a standard driver's capability. The 1150 pF input capacitance at 50 V drain-source means the driver sees a moderate capacitive load; rise and fall times are dominated by the driver's peak current capability, not the FET's Ciss. ## 175°C junction — extended temperature margin The 4 V maximum gate threshold at 50 µA drain current is typical for standard-threshold logic-level FETs — the 10 V drive voltage for minimum Rds(on) is the normal operating point. ## DPak (TO-252) — surface-mount power layout The DPak (TO-252) package has three leads plus a drain tab. The tab is the primary thermal path — the PCB copper area under it sets the junction-to-ambient thermal resistance. A 1-inch-square copper pad on a 2-oz board keeps the junction below 125°C at 25 A continuous in still air.","metaTitle":"IRFR3806TRPBF HEXFET N-Channel MOSFET, 60V 43A DPak","metaDescription":"IRFR3806TRPBF N-channel HEXFET MOSFET, 60V drain-source, 43A continuous, 15.8 mOhm Rds(on) at 10V.
