Groomed for switchmode power supplies, the latest family of SBR power rectifiers offer what is said to be industry-leading ultra-low forward voltages and a safe operating area that results in efficiency increases when compared to existing industry-standard rectifiers. The family provides up to an 85% higher reverse avalanche energy rating, which allows for greater optimization and higher reliability in applications such as OR-ing and secondary rectification in ac/dc and dc/dc power supplies. The components address the adoption of current efficiency requirements like the 80 PLUS and Energy Star 4.0. The SBR30U30CT SBR targets secondary rectification for 3.3V and 5V output voltages in SMPS supplies. With the 85% higher reverse avalanche rating, designers can use this to gain higher overall efficiency by using a 30V device to replace many of the traditional 45V Schottky devices. The device achieves a continuous forward current rating of 30A with an ultra-low forward-voltage drop, and a maximum junction temperature of 150°C. For higher power applications, the SBR40U45CT and SBR60A60CT are available. DIODES INC., Westlake Village, CA. (805) 446-4800.
