At 125°C junction — a realistic operating point in a 375 W dissipation budget — Rds(on) typically rises by a factor of 1.6 to 1.8. Budget 35–40 mOhm hot for loss calculations, not the cold headline. Gate charge is 150 nC at 10 V. That is a moderate Qg for a 200 V, 72 A die — expect a gate-driver capable of sourcing 2–3 A peak to keep switching edges clean at 50–100 kHz. The 5380 pF input capacitance at 50 V Vds confirms the driver sees a significant capacitive load. ## Sourcing and quoting for the BOM line The through-hole TO-262 package is a standard pick-and-place candidate for wave-solder assembly.","metaTitle":"IRFSL4127PBF HEXFET N-Ch MOSFET, 200V 72A TO-262","metaDescription":"IRFSL4127PBF HEXFET N-Channel MOSFET, 200V Vdss, 72A Id, 22mOhm Rds(on) at 10V.
