意法半导体整流器二极管旨在针对目标功能提供各种不同的VF/Qrr 权衡应用性能。意法半导体整流器系列的最小功耗完全适用于电源整流、旁路、升压、自举、续流和高频整流功能。在这些通用功能中,拓扑演化(如:共振或多级)总是伴随着合适的设计。超高速整流器属于STPOWER系列。

这是意法半导体二极管制造业的支柱,旨在为我们过去、现在和将来关注的所有领域的客户提供服务,包括汽车、工业、计算机、消费及电器。

      

我们最好的双极超高速整流器二极管取得了重大的研发进展,如:用于谐振转换器的“RQ”软二极管系列。

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.
