The ST rectifier diode designs deliver performance for applications with very different VF/Qrr trade-offs depending on targeted functions. The minimal power losses of the ST rectifiers range is totally adapted to mains rectification, bypass, boost, bootstrap, freewheel and HF rectification functions. Inside these generic functions, the topology evolution in e.g. resonance or multilevel is followed constantly by suited designs.
This is backed-up by the ST diodes manufacturing industry aimed at serving our customers of all segments, automotive, industrial, computer, consumer and appliance included in a past, present and future focus.
Our best bipolar ultrafast rectifier diodes maintain heavy R&D progress illustrated here by the ‘RQ’ soft diode series for resonant converters.
In 1-mm thick SOD123Flat and SOD128Flat packages
For high-power SMPS, snubber circuits, free-wheeling
for high-power industrial supplies
Up to -15% cost effective solution
Ever lower Qrr, cost-efficient alternative to SiC diodes
New 600V ‘RQ’ diodes improve creepage distance and reduce EMI
These 600 V, 15- to 30-amp diodes are also available in an automotive-grade ‘RQ’ series, suited for on-board battery chargers (OBC) and 2- or 3-wheeler battery chargers.
