As the first devices in a family of super barrier rectifiers (SBR) designed for automotive applications, Diodes’ rugged rectifiers enable automotive designers to increase the reliability of motor control, display panel, and LED lighting circuits. The SBRs feature a lower forward voltage drop, improved avalanche rating, and higher safe operating area (SOA) than alternative Schottky or ultrafast diode alternatives, claims the company. Using Diodes’ SBR technology, the AECQ101-qualified SBR20A60CTBQ, SBR30A45CTBQ, and SBR3045CTBQ rectifiers handle output currents of 20 and 30 A and are provided in the industry-standard TO-263 package, while the SBR1045D1Q is rated for 10 A and comes in the slightly smaller TO-252 package. With the SBRs’ low VF, circuit power efficiency can be significantly improved and much cooler operation achieved.
