At 18A the I²R loss hits roughly 36W, but the 57W package dissipation limit at the case means the thermal pad and PCB copper area set the real current ceiling — derate for ambient temperature. Total gate charge is 32 nC at 10V, which translates to a few mA of drive current at moderate switching frequencies — a basic gate-driver IC or a totem-pole from a PWM controller handles it. Input capacitance is 650 pF at 25V Vds, so the driver sees a light capacitive load; rise and fall times stay tight without a pre-driver. ## DPak surface-mount — layout and thermal path Housed in the TO-252-3 (DPak) package, the IRFR5505TRPBF mounts on the board with the tab as the drain connection and the primary heat path.
