600V 150mΩ Cascode GaN FET in TO-220

The TPH3206PS 600V 150mΩ gallium nitride (GaN) FET is a normally-off device. Transphorm GaN FETs offer better efficiency through lower gate charge, faster switching speeds, and smaller reverse recovery charge, delivering significant advantages over traditional silicon (Si) devices. The TPH3206PS is offered in an industry-standard 3 lead TO-220 with a common source package configuration.
