10-30A rectifiers provide fast & soft recovery characteristics

Vishay has introduced 16 10-30A FRED Pt Hyperfast and Ultrafast recovery rectifiers in the low-profile SMPD (TO-263AC) package. Combining extremely fast and soft recovery characteristics with low leakage current and low forward voltage drop, the rectifiers reduce switching losses and over-dissipation in automotive and telecomms 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 200 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 TO-263 (D²PAK) package, the devices offer a lower package height of under 1.7mm for increased power density and efficiency and to enable slimmer end products. 

Specified for output and snubber operation, the FRED Pt rectifiers are optimised for DC/DC converters, PFC, low-voltage inverters, and chopper motor drives in ECUs, ABS, LED lighting, and HID lighting, in addition to telecomms 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 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 suitable for automated placement and allow for AOI in automotive systems.

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