TransphormHighest Performance, Highest Reliability GaN

TPH3205WSB

650V 49mΩ GaN FET in TO-247

The TPH3205WSB 650V 49mΩ Gallium Nitride (GaN) FET is a normally-off device. 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 TPH3205WSB is offered in an industry-standard 3 lead TO-247 with a common source package configuration.
