Rectifiers ideal for high-frequency SMPSs and DC-DC converters in demanding automotive applications

Littelfuse has introduced a series of Schottky barrier rectifiers designed to outperform conventional switching diodes in commercial, industrial and automotive applications. DST Series Schottky barrier rectifiers combine ultra-low forward voltage drop, high current handling, high junction temperature capability, and low leakage performance in a compact TO-277B surface mount package. For automotive applications up to 10A, it offers the same or better performance as those provided in D-PAK packaging, with a footprint that’s only one-third of the size. View the video. Typical applications for series include high-frequency SMPSs and DC-DC converters found in automotive applications such as ADAS (such as cameras, sensors, and electronic control units), infotainment systems (GPS, audio, etc.), LCD displays, and LED headlights and tail lights. Other applications include polarity protection diodes and reverse blocking diodes. “The DST Series of Schottky Barrier Rectifiers includes devices that are AEC-Q qualified and manufactured in accordance with the TS/ISO16949 automotive quality management system standard,” said Zhiwei Wang, product manager at Littelfuse. “That means circuit designers for the automotive industry can design these parts into their next generation of products with confidence.”
