X-Class Power MOSFETs

IXYS X-Class Power MOSFETs are high-power density N-Channel Enhancement Mode MOSFETs. They are easy to mount and have a low R_DS(ON) and Q_Gwith a low package inductance. Typical applications include switch-mode and resonant-mode power supplies, DC-DC converters and PFC circuits.
