Ultrafast rectifiers increase power density, performance efficiency and device reliability

Vishay Intertechnology has introduced new 200V FRED Pt Ultrafast recovery rectifiers in the thermally efficient FlatPAK 5x6 package with a low profile of <1mm. 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 providing high power density and efficiency for telecom and automotive applications. The rectifiers join their low profiles with high forward current ratings of 6A (2 x 3A) for the VS-6DKH02-M3 and VS-6DKH02HM3 and 8A (2 x 4A) for the VS-8DKH02-M3 and VS-8DKH02HM3. Configured as dual-die rectifiers with separate cathode connections, the devices enable designers to simplify PCB layouts by using one package instead of two smaller ones. The company's FlatPAK offers the standard footprint of 5x6 QFN (quad flat no lead) packages broadly used already by other technologies, including MOSFETs, and allows for different circuit topologies. The new rectifiers offer an MSL moisture sensitivity level of 1, per J-STD-020, LF maximum peak of +260C. RoHS-compliant and halogen-free, the devices are perfect for automated placement and provide for automated optical inspection (AOI) in automotive systems.
