MOSFETs cut conduction and switching losses for multiple benefits

International Rectifier’s family of 30V HEXFET MOSFETs deliver enhanced efficiency under both full-load and lightload conditions.

These allow higher performance and replace paralleled MOSFETs for reduced board space requirements and assembly costs.

These improvements are the product of architectural enhancements to IR’s HEXFET technology, delivering simultaneous savings in on-resistance and gate charge.

Depending on the application, the new HEXFET devices enable a simplified costeffective performance upgrade path for existing designs. They are particularly suited to point-ofload synchronous buck converter applications requiring current-handling capability between 4A and 12A per MOSFET. The low conduction losses also improve thermal performance, allowing the use of standard SO-8 and DPAK packages to maximise cost savings at high power ratings.
