Vishay Intertechnology FRED Pt® Ultrafast Rectifiers in SlimDPAK Save Space, Increase Power Density, Improve Thermal Performance

Wednesday, November 22, 2017

 

Vishay Intertechnology, Inc. (NYSE: VSH) has introduced 13 new 200 V and 600 V FRED Pt® Ultrafast recovery rectifiers in the eSMP® series SlimDPAK (TO-252AE) package, each available in Automotive Grade and commercial / industrial versions. Offering lower profiles and better thermal performance than devices in the DPAK (TO-252AA), the Vishay Semiconductors rectifiers deliver high power density and efficiency for automotive and telecom applications.

 

The newly released devices combine a low 1.3 mm profile with high forward current ratings to 10 A for 200 V rectifiers and 15 A for 600 V rectifiers. Footprint-compatible with the DPAK package, the devices’ profile is 43 % lower to enable slimmer end products, while their heatsink area is 14 % larger for lower thermal resistance. In addition, new 15 A rectifiers provide an alternative to devices in the D2PAK (TO-263AB) package.

 

The rectifiers’ FRED Pt technology enables ultrafast recovery times down to 14 ns, low reverse recovery charge, and soft recovery features over the entire working temperature range of -55 °C to +175 °C. The devices’ low forward voltage drop down to 0.71 V at 4 A reduces power losses and improves efficiency. Typical applications for the AEC-Q101 qualified Automotive Grade rectifiers include DC/DC converters in automotive engine control units (ECU), anti-lock braking systems (ABS), and HID and LED lighting, while commercial / industrial devices are optimized for telecom power supplies.

 

The new rectifiers feature a MSL moisture sensitivity level of 1, per J-STD-020, LF maximum peak of +260 °C. RoHS-compliant and halogen-free, the devices are ideal for automated placement and allow for automated optical inspection (AOI) in automotive systems.
