International Rectifier has launched a series of 150 and 200V Hexfet power MOSFETs designed to offer ultra low gate charge for industrial applications including switch mode power supplies (SMPS), uninterruptable power supplies (UPS), inverters and DC motor drives. IRs 150V MOSFETs offer up to 59 per cent lower total gate charge than competing devices while the new 200V MOSFETs feature up to 33 per cent 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. IRs new 150V and 200V MOSFETs are optimized for fast switching circuits where switching losses are critical, and, are therefore 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.
The new MOSFETs are qualified to industrial grade and moisture sensitivity level 1 (MSL1). The devices are available in TO220, D2PAK, TO262, DPAK and IPAK packages, offered lead free and are RoHS compliant.
