Fairchild has introduced synchronous rectification mosfets aimed at meeting the Energy Star 80 Plus Silver specification. The FDP025N06, FDB024N06, FDP032N08, FDB031N08, FDP047N10, and FDB047N10 60 to 100V devices.

"Compared to traditional diode solutions that are limited by higher voltage drops during high current conduction modes, these mosfets with their low on-resistance - 1.9mΩ typical with the FDP025N06 - offer a 1% improvement in efficiency and meet the 80 Plus Silver specification for high power applications such as desktop PCs, servers and telecom power," said Fairchild.

"To qualify for this label, computing applications must have power supplies that are 85% efficient at 20% rated output load."

The devices are Pb-free and characterised for moisture sensitivity in accordance with the joint IPC/JEDEC standard J-STD-020.
