Vishay Intertechnology’s FRED Pt® Ultrafast Rectifiers in FlatPAK™ 5x6 Package

Vishay introduced new 200 V FRED Pt® Ultrafast recovery rectifiers in the thermally efficient FlatPAK™ 5x6 package with a low profile of < 1 mm. With long term reliability assured through 2000 hours of high temperature reverse bias (HTRB) testing, the commercial / industrial VS-6DKH02-M3 and VS-8DKH02-M3 and Automotive Grade VS-6DKH02HM3 and VS-8DKH02HM3 deliver high power density and efficiency for automotive and telecom applications.

The rectifiers combine their low profiles with high forward current ratings of 6 A (2 x 3 A) for the VS-6DKH02-M3 and VS-6DKH02HM3 and 8 A (2 x 4 A) for the VS-8DKH02-M3 and VS-8DKH02HM3. Configured as dual-die rectifiers with separate cathode connections, the devices allow designers to simplify PCB layouts by utilizing one package instead of two smaller ones. Vishay’s FlatPAK features the standard footprint of 5 x 6 QFN (quad flat no lead) packages widely used already by other technologies, such as MOSFETs, and allows for different circuit topologies.

The rectifiers’ FRED Pt technology enables ultrafast recovery times down to 25 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 0.7 V reduces power losses and improves efficiency.
