On-resistance and gate drive — sizing the conduction and switching loss
Maximum on-resistance is 210 mOhm at 5.6 A drain current with 10 V gate drive. This is the conduction loss floor at 25°C junction; actual Rds(on) rises with temperature per the normalised curve in the datasheet, so the thermal budget must account for the higher resistance at the operating junction temperature. Total gate charge is 25 nC at 10 V. At a 100 kHz switching frequency the gate driver must supply 2.5 mA average current, which is well within the capability of a standard gate-driver IC. The 330 pF input capacitance at 25 V drain-source gives a rough switching-speed ceiling when paired with the driver's source/sink resistance.
Temperature range and thermal limits — harsh-environment fit
Maximum power dissipation is 48 W at case temperature 25°C, derated linearly above that.
Store the reels dry — the D-Pak is moisture-sensitive and requires bake before reflow if the moisture-barrier bag is compromised.
