IR's 150V and 200V MOSFETs with low gate charge for industrial applications

IR has introduced a series of 150V and 200V HEXFET power MOSFETs with very low gate charge (Qg) for industrial applications including switch mode power supplies (SMPS), uninterruptable power supplies (UPS), inverters and DC motor drives.

IR claims, when compared to the competing devices 150V MOSFETs offer up to 59 percent lower gate charge and 200V MOSFETs offer up to 33 percent lower gate charge.

"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.
