Vishay Siliconix TrenchFET® Gen III Power MOSFETs with TurboFET™

The Vishay Siliconix TrenchFET® Gen III Power MOSFET family offers the industry's lowest on-resistance and on-resistance times gate charge for a device with this voltage rating in the PowerPAK® SO-8 package type. The Vishay Siliconix TrenchFet Gen III Power MOSFET improves greatly on the performance of the closest competing devices. The lower on-resistance and gate charge of the TrenchFet Gen III Power MOSFET translate into lower conduction and switching losses. Several devices in the TrenchFET family are also equipped with TurboFET™ technology, which won the EN-Genius award for Best Improvement in Power Devices. Vishay Siliconix TrenchFET devices are used as the low-side MOSFET in synchronous buck converters and in secondary synchronous rectification and OR-ing applications.
