At a 175 °C junction temperature, expect the on-resistance to roughly double, so budget the conduction loss for the hot case, not the cold spec. ## Gate charge and switching loss Total gate charge is 65 nC at Vgs = 10 V. For a hard-switched converter at 100 kHz, the average gate drive current needed is 6.5 mA — well within a standard driver's capability, but the peak current during the Miller plateau determines the transition time and crossover loss.","metaTitle":"AUIRFZ44VZS MOSFET, N-Ch 60V 57A D2PAK, 12mOhm Rds(on)","metaDescription":"AUIRFZ44VZS N-Channel HEXFET MOSFET, 60V, 57A, 12mOhm Rds(on) at 10V.
