TransphormHighest Performance, Highest Reliability GaN

TPH3205WSBQA

650V 49mΩ AEC-Q101 Qualified GaN FET in TO-247

The TPH3205WSBQA 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.

The device is also automotive qualified, having passed the Automotive Electronics Council’s AEC-Q101 stress tests for automotive-grade discrete semiconductors.

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

The TPH3205WSBQA is offered in an industry-standard 3 lead TO-247 with a common source package configuration.
