Ultrafast rectifiers increase power density and efficiency

FRED Pt rectifiers from Vishay which are available from Rutronik UK, significantly increase power density, performance efficiency and device reliability. They come in a thermally efficient FlatPAK five by six package, with a low profile of less than one millimeter.

The rectifiers are available in commercial, industrial and automotive grade versions with either two by three amps or two by four amps forward current for each type.

By delivering high power density and efficiency, they are ideally suited for automotive and telecom applications. The long term reliability of the rectifiers is assured through 2000 hours of high temperatures reverse bias (HTRB) testing.

Configured as dual-die rectifiers with separate cathode connections, they allow designers to simplify PCB Layouts by utilizing one package instead of two smaller ones.

By using a standard footprint of five by six QFN (quad flat no lead) package, a range of different circuit topologies are possible.

A low forward voltage drop down to 0.7V reduces power losses and improves the efficiency.

They offer 200V reverse voltage, ultrafast recovery times down to 25ns, a low reverse recovery charge and soft recovery features.

The operating temperature range is between -55 and +175°C. The rectifiers are RoHS-compliant, halogen-free and have a MSL moisture sensitivity level of one, the LF maximum peak is at +260°C.
