SBRs improve efficiency of daytime running lights
The patented technology of Diodes Inc’s new super barrier rectifiers (SBR)s can significantly reduce power loss and lower operating temperatures in automotive applications. The company now has introduced two such SBRs – the SBR10M100P5Q and the SBR8M100P5Q – that can be used as a recirculating diode in DC-to-DC buck-boost converters for automotive daytime running light (DRL) applications. In such an application, they can improve system efficiency by 5% and at the same time keep the operating temperatures at bay.

The SBR10M100P5Q (10A, 100V) and SBR8M100P5Q (8A, 100V) feature low forward voltage drop, ultra-low reverse leakage, and fast switching speeds, which combine to reduce system efficiency losses by up to 30%, when compared to Schottky barrier diode technology, reducing energy consumption and running costs. Generating less heat reduces the cost of cooling components and provides a more reliable end product.

SBR technology is a drop-in replacement for existing Schottky diodes; it can deliver immediate benefits without any costly redesign effort, and reduces time to market for existing systems that need to meet more stringent limits. In addition to DRL, the SBR10M100P5Q and SBR8M100P5Q can be deployed in other applications as they deliver superior efficiency and reliability performance over Schottky diodes in polarity protection, switching and blocking, as well as AC-DC and DC-DC conversion. 

The SBR10M100P5Q and SBR8M100P5Q SBR diodes are automotive-compliant to AEC-Q101 and can be supplied in accordance with PPAP requirements.
