TPH3208PS

650V 110mΩ GaN FET in TO-220

The TPH3208PS 650V 110mΩ gallium nitride (GaN) FET is a normally-off device. It combines a low voltage silicon MOSFET—with industry-leading threshold voltage for increased noise immunity—with the market’s most reliable depletion mode GaN FET. Transphorm GaN offers improved efficiency over silicon, through lower gate charge, lower crossover losses, and smaller reverse recovery charge.

The TPH3208PS is offered in an industry-standard 3 lead TO-220 with a common source package configuration.
