16 state-of-the-art Vishay 10A to 30A FRED Pt Hyperfast and Ultrafast Recovery Rectifier options in the low-profile SMPD (TO-263AC) package have been added to the New Yorker Electronics portfolio. Named a 2017 Vishay Super 12 Featured Product, it combines 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.

The FRED Pt rectifiers are available in AEC-Q101-qualified and standard versions. They offer reverse voltages of 200V and 600V, reverse recovery time down to 25ns and typical forward voltage drop down to 0.75V in single- and dual-die configurations.

Footprint-compatible with the TO-263 (D2PAK) package, the devices offer a lower package height of <1.7mm for increased power density and efficiency, enabling slimmer end products.

Specified for output and snubber operation, the FRED Pt rectifiers are optimised 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, LF maximum peak of +260°C, meet the JESD 201 class 2 whisker test.

They are RoHS-compliant, halogen-free with lead (Pb)-free terminations. The rectifiers are ideal for automated placement and allow for automated optical inspection (AOI) in automotive systems.

Applications include Inverters and Converters, High Power Supplies and Large Drives, Renewable Energy, Welding Equipment, AC Harmonic Filters and Uninterruptible Power Supply (UPS) Systems
