TransphormHighest Performance, Highest Reliability GaN


650V 240mΩ GaN FET in PQFN88

The TP65H300G4LSG 650V 240mΩ gallium nitride (GaN) FET is a normally-off device. Transphorm GaN FETs offer better efficiency through lower gate charge, faster switching speeds, and smaller reverse recovery charge, delivering significant advantages over traditional silicon (Si) devices. The TP65H300G4LSG is offered in an industry-standard 8×8 PQFN with a common source package configuration.
