New 600V ‘RQ’ diodes improve creepage distance and reduce EMI

Thanks to the high-voltage D²PAK package, our new diode series improves the creepage distance and facilitates compliance with the IEC 60664-1 worldwide standard. ST now offers 600 V ‘RQ’ diodes (Rapid & Quiet) – providing a minimum of 3.48 mm between the anode and cathode instead of only 1.38 mm for a standard D²PAK device. Developed for electric vehicle (EV) charging stations, industrial converters, high-power SMPS, snubber circuits and for free-wheeling, these diodes feature a unique trade-off between a soft reverse recovery to reduce electromagnetic interference (EMI) and a low forward voltage (VF) to gain efficiency in all modes of resonant-based topologies.
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.
