Littlefuse Inc., the global leader in circuit protection, has unveiled a series of Schottky Barrier Rectifiers. These devices have been designed to outperform conventional switching diodes in commercial, industrial, as well as, automotive applications. The series combines ultra-forward voltage drop, high current handling, high junction temperature capability, and low leakage performance in a compact TO-277B surface mount package.

 

As far as the automotive applications are concerned, for up to 10 A, it offers an equal level of performance seen in D-PAK packaging, with a footprint that’s one-third of the size. Moving on, some typical applications for these Rectifiers include high-frequency switch-mode power supplies (SMPSs) and DC-DC converters found in automotive applications like-

 

• Infotainment system

• LCD displays

• LED headlights 

• Tail lights

 

Other applications include polarity protection diodes and reverse blocking diodes.

 

 The ultra-low forward voltage drop (VF) reduces thermal and electrical conduction losses, thereby improving system efficiency.

 Provide high-speed switching for use in very high-frequency applications with minimal switching loss.

 High junction temperature capability ensures high reliability in high ambient temperatures and applications with minimal cooling available.

 

“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.”

DST Series Schottky Barrier Rectifiers are available in surface mount TO-277B packages in tape and reel format in quantities of 5,000. Sample requests can be placed through authorized Littelfuse distributors worldwide.
