Super barrier rectifier diodes reduce power in automotive lights

The SBR10M100P5Q and SBR8M100P5Q are automotive-compliant super barrier rectifier (SBR) diodes by Diodes. They use patented and proprietary technology to significantly reduce power loss and lower operating temperatures in automotive applications, says Diodes. When used as a recirculating diode in DC/DC buck-boost converters for automotive daytime running light (DRL) applications, the diodes devices can improve system efficiency by up to five per cent while reducing operating temperatures by up to five degrees C.

The SBR10M100P5Q (10A, 100V) and SBR8M100P5Q (8A, 100V) have low forward voltage drop, low reverse leakage, and fast switching speeds, which combine to reduce system efficiency losses by up to 30 per cent, when compared to Schottky barrier diode technology, says Diodes. The result is reduced energy consumption and running costs. Another benefit is that generating less heat reduces the cost of cooling components, adds Diodes.

SBR technology is a drop-in replacement for existing Schottky diodes. It can deliver immediate benefits without any costly redesign effort, claims Diodes 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 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. They are provided in the PowerDI 5 package.
