Input capacitance is 1690 pF at 25 V drain-source, which together with the 65 nC gate charge defines the switching loss profile — the driver must source and sink enough peak current to charge and discharge this capacitance within the dead-time budget.","metaTitle":"IRFZ44VZL HEXFET N-Channel MOSFET, 60V 57A TO-262","metaDescription":"IRFZ44VZL HEXFET N-Channel MOSFET, 60V drain-source, 57A continuous drain, 12mOhm Rds(on) at 34A.
