The TP65H300G4LSGB 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 TP65H300G4LSGB is offered in an industry-standard PQFN88 with a Kelvin source and common source package configuration.
