Utilizing Diodes' SBR technology, the AECQ101 qualified SBR20A60CTBQ, SBR30A45CTBQ and SBR3045CTBQ rectifiers handle output currents of 20 A 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.
The SBRs' low VF means circuit power efficiency can be significantly improved and much cooler operation achieved, the vendor of the SBR devices promises. The resulting improvement in reliability is further increased by the devices' higher reverse avalanche rating, that provides greater protection against transient voltage spikes and its lower reverse leakage that provides a higher SOA and guards against thermal runaway in high temperature operating conditions.
The automotive Super Barrier Rectifiers from Diodes Incorporated are priced from $0.45 USD each in 10k quantities. Further information is at www.diodes.com.
