15 June 2011 Rectifiers increase reliability in automotive applications Diodes Incorporated has announced the first devices in a family of Super Barrier Rectifiers (SBR) designed for automotive applications. The company claims the devices have a lower forward voltage drop, improved avalanche rating and higher safe operating area than alternative Schottky or ultrafast diode alternatives. The rugged rectifiers are designed to enable automotive designers to increase the reliability of motor control, display panel and LED lighting circuits. Utilising Diodes' patented SBR technology, the AECQ101 qualified SBR20A60CTBQ, SBR30A45CTBQ and SBR3045CTBQ rectifiers handle output currents of 20 and 30A and are provided in an industry standard TO-263 package, while the SBR1045D1Q is rated for 10A and comes in a slightly smaller TO-252 package. The SBRs' low VF means circuit power efficiency can be improved and cooler operation achieved. The resulting improvement in reliability is further increased by the devices' higher reverse avalanche rating, said to provide greater protection against transient voltage spikes. Its lower reverse leakage provides a higher SOA and guards against thermal runaway in high temperature operating conditions.
