AN605 vishay SiliconixDocument Number: MOSFET Basics: Understanding MOSFET Characteristics AssociatedWith The Figure of MeritJess Brown, Guy MoxeyINTRODUCTIONP ower mosfets have become the standard choice as themain switching device for low-voltage (<200 V) switchmodepower-supply (SMPS) converter applications. However usingmanufacturers datasheets to choose or size the correctdevice for a specific circuit topology is becoming increasinglydifficult. The main criteria for MOSFET selection are the powerloss associated with the MOSFET (related to the overallefficiency of the SMPS) and the Power -dissipation capabilityof the MOSFET (related to the maximum junction temperatureand thermal performance of the package).
