Vishay Intertechnology has introduced new 200 V FRED Pt Ultrafast recovery rectifiers in the thermally efficient FlatPAK 5×6 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 released by Vishay Intertechnology 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 respectively. 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 Intertechnology FlatPAK features the standard footprint of 5×6 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.
The applications for the VS-6DKH02HM3 & VS-8DKH02HM3 rectifiers include
- DC/DC converters in automotive engine control units (ECU),
- Anti-lock braking systems (ABS), and
- HID and LED lighting,
While the VS-6DKH02-M3 and VS-8DKH02-M3 are optimized to deliver high power density and efficiency for automotive and telecom applications.
The new rectifiers feature an 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.
