A 1 A driver can charge the gate in about 110 ns, supporting switching frequencies up to the low tens of kilohertz before driver losses dominate. The 4560 pF input capacitance at 25 V drain-source confirms the gate-driver output impedance needs to be low enough to avoid miller plateau ringing. ## 175 °C junction — usable headroom with a thermal caveat However, the D²Pak (PG-TO263-3) on a standard FR-4 board with 1 oz copper has a junction-to-ambient thermal resistance around 60–80 °C/W — so the practical continuous current at 85 °C ambient is well below the 45 A headline figure. The 330 W power dissipation rating assumes the case is held at 25 °C, which requires a heatsink or forced air.","metaTitle":"IRFS4229TRLPBF HEXFET N-Channel MOSFET, 250 V, 45 A, D2PAK","metaDescription":"IRFS4229TRLPBF HEXFET N-channel MOSFET, 250 Vdss, 45 A continuous drain, 48 mOhm Rds(on) at 10 V.
