TransphormHighest Performance, Highest Reliability GaN

TP65H300G4LSG  SuperGaN

650V 35mΩ GaN FET (SuperGaN™) in PQFN88

Review this product

The TP65H300G4LSG 650V 240mΩ Gallium Nitride (GaN) FET is a normally-off device built using Transphorm’s Gen IV platform. It combines state-of-the-art high voltage GaN HEMT and low voltage silicon MOSFET technologies—offering superior reliability and performance.

Transphorm GaN offers improved efficiency over silicon, through lower gate charge, lower crossover loss, and smaller reverse recovery charge.

The TP65H300G4LSG is offered in an industry-standard PQFN88 with a common source package configuration.
