IR Introduces 150V and 200V MOSFETs with Very Low Gate Charge For Industrial Applications

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.

IR’s 150V MOSFETs offer up to 59 percent lower total gate charge than competing devices while the new 200V MOSFETs feature up to 33 percent lower total gate charge than competing devices.

“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.

The new MOSFETs are qualified to industrial grade and are moisture sensitivity level 1 (MSL1). The devices are available in TO220, D2PAK, TO262, DPAK and IPAK packages, offered lead free and are RoHS compliant.
