Recently, Vishay Intertechnology, Inc. (NYSE: VSH) announced the launch of 13 200V to 600V FRED Pt® ultra-fast recovery rectifiers. Both are available in the eSMP series SlimDPAK (TO-252AE) package. Each product is available in automotive and commercial/industrial versions. Vishay Semiconductors rectifiers are thinner than conventional DPAK (TO-252AA) packages, offer better thermal performance, higher power density and higher efficiency for automotive and communications applications.

The device released today is only 1.3mm high, the forward current of the 200V rectifier is up to 10A, and the 600V rectifier is 15A. The device's footprint is the same as that of the DPAK package, which is 43% thinner, making the final product lighter and thinner, while its heat dissipation area is 14% larger, resulting in lower thermal resistance. In addition, the new 15A rectifier can replace the D2PAK (TO-263AB) package.

The rectifier uses FRED Pt technology to achieve an ultra-fast recovery time of 14ns and an ultra-small reverse recovery charge, enabling soft recovery over the entire operating temperature range of -55°C to +175°C. The forward voltage drop of the device at 4A is only 0.71V, which effectively reduces power loss and improves efficiency. Rectifiers are AEC-Q101 certified to automotive grade standards. Typical applications include automotive engine control unit (ECU), anti-lock brake system (ABS), HID and DC/DC converters in LED lighting, and commercial/industrial versions. The product is suitable for communication power.

The new rectifier has a moisture sensitivity rating of Class 1 of the J-STD-020 standard and a peak LF of +260 °C. The device is RoHS compliant and halogen-free, making it ideal for automated placement and automatic optical inspection (AOI) in automotive systems.

Samples are available for the new ultra-fast recovery rectifiers and will be available in volume production in September 2017. The lead time for major orders is eight to ten weeks.
