Vishay's SMPD FRED Pt rectifiers increase power density and efficiency
Vishay Intertechnology introduced 16 new 10 A to 30 A FRED Pt Hyperfast and Ultrafast recovery rectifiers in the low-profile SMPD (TO-263AC) package. Combining extremely fast and soft recovery characteristics with low leakage current and low forward voltage drop, the Vishay Semiconductors rectifiers reduce switching losses and over-dissipation in automotive and telecom applications while providing a high-density alternative to the TO-263 (D²PAK) package.
Available in AEC-Q101-qualified and standard versions, the FRED Pt rectifiers released today offer reverse voltages of 200 V and 600 V, reverse recovery time down to 25 ns, and typical forward voltage drop down to 0.75 V in single- and dual-die configurations. Footprint-compatible with the TO-263 (D²PAK) package, the devices offer a lower package height of < 1.7 mm for increased power density and efficiency and to enable slimmer end products.
Specified for output and snubber operation, the FRED Pt rectifiers are optimized for DC/DC converters, power factor correction (PFC), low-voltage inverters, and chopper motor drives in automotive engine control units (ECUs), antilock braking systems (ABS), LED lighting, and HID lighting, in addition to telecom DC/DC bricks. The devices feature a planar structure and platinum-doped lifetime control to guarantee high overall performance, ruggedness, and reliability characteristics in these applications. The components offer an operating junction temperature from -55 °C to +175 °C for a more robust design.
The devices provide an MSL moisture level of 1 per J-STD-020, feature an LF maximum peak of +260 °C, meet the JESD 201 class 2 whisker test, and are RoHS-compliant and halogen-free. The rectifiers are ideal for automated placement and allow for automated optical inspection (AOI) in automotive systems.
Samples and production quantities of the new FRED Pt rectifiers are available now, with lead times of nine weeks for larger orders. Pricing for U.S. delivery only starts at $0.31 per piece for 16 A, 200 V devices.
