EL SEGUNDO, Calif. — International Rectifier, IR® (NYSE: IRF), a world leader in power management technology, today introduced a series of 150V and 200V HEXFET® power MOSFETs with ultra low gate charge (Qg) for industrial applications including Switch Mode Power Supplies (SMPS), uninterruptable power supplies (UPS), inverters and DC motor drives.

“As DC-DC power converter applications advance and switching frequencies increase, input capacitance and gate charge play a significant role in overall efficiency. IR’s new 150V and 200V MOSFETs are optimized for fast switching circuits where switching losses are critical, and, therefore, are well suited as a primary switch for isolated DC-DC converters for telecom applications or driving light load efficiency in any advanced DC-DC application,” said Brian LaValle, marketing manager for IR’s Power Management Devices Business Unit.
