TrenchFET® Gen III Power MOSFETs Vishay Semiconductor TrenchFET® Gen III Power MOSFETs offer low on-resistance and on-resistance times gate charge in PowerPAK® SO-8, PowerPAK 1212-8, and SO-8 package types. The lower on-resistance and gate charge of TrenchFET Gen III Power MOSFETs translate into lower conduction and switching losses. Several devices in the TrenchFET family are also equipped with TurboFET™ technology. Vishay Semiconductor TrenchFET devices are used as the low-side MOSFET in synchronous buck converters and in secondary synchronous rectification and OR-ing applications.
