Transphorm’s Technology

Normally-off/Cascode – Normally-off devices are considered safer than normally-on devices. Transphorm pairs it’s normally-on, high-voltage GaN FET with a normally-off, low-voltage Si MOSFET. This creates a hybrid device that is normally-off but still compatible with Si drivers for added ease of use. This results in an overall fast-switching device with low conduction, switching and output losses. One important advantage of a Cascode switch is that no special driver is required.
