This is a PDF document about FQD10N20C / FQU10N20C 200V N-Channel MOSFET. The document describes the features and characteristics of these N-Channel enhancement mode power field effect transistors, including low on-state resistance, superior switching performance, and ability to withstand high energy pulse in the avalanche and commutation mode. These devices are well suited for high efficiency switching DC/DC converters, switch mode power supplies, DC-AC converters for uninterrupted power supplies, and motor controls.
