PowerTrench® MOSFETs

PowerTrenchFairchild was an early pioneer of trench MOSFETs in the 1990s. Since then, we have been perfecting MOSFET technology and manufacturing to develop a large portfolio of thousands of products for use in any application. Fairchild’s PowerTrench® MOSFETs deliver best-in-class performance, improved FOM (figure of merit), and pin-to-pin compatibility for ease of use. Designers continue to choose our MOSFETs for high quality and reliability, design support, and consistent availability.

Our latest 100V PowerTrench® MOSFETs deliver the lowest RDSon and Qrr in the voltage class with the fastest reverse recovery to enable higher system efficiencies. The shielded-gate structure provides charge balance and soft body diode performance is able to eliminate snubber circuit or replace higher voltage-rated MOSFETs by minimizing undesirable voltage spikes in synchronous rectification. Fairchild PowerTrench MOSFETs provide designers the opportunity to significantly increase system efficiency and power density in synchronous rectification applications.
