Vishay's new FRED Pt Ultrafast rectifier can greatly improve power density, performance efficiency and equipment reliability

These 200V devices are available in automotive grade and commercial/industrial versions, with a height of less than 1mm and a single cathode structure up to 8A

Recently, Vishay Intertechnology, Inc. announced the launch of its new 200V FRED Pt® Ultrafast Fast Recovery Rectifiers - VS-6DKH02-M3 and VS-8DKH02-M3, automotive grade VS-6DKH02HM3 and VS-8DKH02HM3. The new rectifier is available in a thermally efficient FlatPAKTM 5x6 package and has a height of less than 1mm. Commercial/industrial VS-6DKH02-M3 and VS-8DKH02-M3, as well as automotive grades VS-6DKH02HM3 and VS-8DKH02HM3, both undergo 2000 hours of high temperature reverse bias testing (HTRB) with long-term reliability, high power density And high efficiency, suitable for automotive and communications applications.

The rectifiers released today are small in size and have a large forward current. The forward current of the VS-6DKH02-M3 and VS-6DKH02HM3 is 6A (2x3A), and the forward current of the VS-8DKH02-M3 and VS-8DKH02HM3 is 8A (2 x 4A). ). With a stand-alone cell design, the device can be configured as a dual-die rectifier, replacing two smaller packages with a single package, helping designers to simplify PCB layout. Vishay's FlatPAK has the same standard footprint as the 5 x 6 QFN (quad flat no-lead package). QFN is a widely used package for MOSFETs and other technologies and can use different circuit topologies.

The rectifier uses FRED Pt technology to achieve an ultra-fast recovery time of 25ns, low reverse recovery charge, and soft recovery characteristics over the operating temperature range of -55°C to +175°C. The forward voltage of the device is reduced to 0.7V, reducing power loss and improving efficiency. The VS-6DKH02HM3 and VS-8DKH02HM3 are AEC-Q101 certified. Typical applications include automotive engine control units (ECUs), anti-lock braking systems (ABS), DC/DC converters in HID and LED lighting, commercial/industrial applications. The VS-6DKH02-M3 and VS-8DKH02-M3 are suitable for communication power supplies.

The new rectifier has a moisture sensitivity level of 1 in the J-STD-020 standard, with a peak LF of +260°C. The device is RoHS compliant, halogen-free, and is ideally suited for automated patching and automatic optical inspection (AOI) in automotive systems.
