Vishay Intertechnology Inc. has rolled out 16 10A to 30A FRED Pt Hyperfast and Ultrafast recovery rectifiers. According to the company, the device feature extremely fast and soft recovery characteristics with low leakage current and low forward voltage drop.

The Vishay Semiconductors rectifiers claim to minimise switching losses and over-dissipation in automotive and telecom applications while providing a high-density alternative to the TO-263 (D2PAK) package.

Available in AEC-Q101-qualified and standard versions, the FRED Pt rectifiers offer reverse voltages of 200V and 600V, reverse recovery time down to 25ns, and typical forward voltage drop down to 0.75V in single- and dual-die configurations. Footprint-compatible with the low-profile TO-263 (D2PAK) package, the devices offer a lower package height of < 1.7mm for increased power density and efficiency and to enable slimmer end products, noted the company.

FRED Pt rectifier

Specified for output and snubber operation, the FRED Pt rectifiers are optimised for DC/DC converters, power factor correction (PFC), low-voltage inverters and chopper motor drives in automotive engine control units (ECUs), antilock braking systems (ABS), LED lighting and HID lighting, in addition to telecom DC/DC bricks. The devices feature a planar structure and platinum-doped lifetime control to guarantee high overall performance, ruggedness, and reliability characteristics in these applications. The components offer an operating junction temperature from -55°C to 175°C for a more robust design.

The devices provide an MSL moisture level of 1 per J-STD-020, feature an LF maximum peak of 260°C, meet the JESD 201 class 2 whisker test, and are RoHS-compliant and halogen-free. The rectifiers are geared for automated placement and allow for automated optical inspection (AOI) in automotive systems.

Samples and production quantities of the FRED Pt rectifiers are available with lead times of nine weeks for larger orders.
