Vishay Intertechnology has introduced ten FRED Pt recovery rectifiers, including the industry’s first 3A devices in the SMA package, 3A and 4A devices in the SMB package, and 4A and 5A devices in the SMC package.
The VS-xExx06-M3 devices offer extremely fast and soft recovery. They are also characterized by their low forward-voltage drop and low leakage current, which means that they help the designer to reduce switching losses in products that require high energy efficiency, such as consumer products, LCD TVs, power supplies and lighting ballasts. The devices provide a choice of current ratings, packages and speeds to optimize efficiency in these applications.
With forward currents up to 3A in the SMA package, 4A in the SMB package, and 5A in the SMC package, these rectifiers provide high power density. The ‘U Speed’ Ultrafast rectifiers offer the advantage of lower forward voltage, while the ‘H Speed’ Hyperfast devices provide lower reverse-recovery charge.
The rectifiers feature a planar structure and platinum-doped lifetime control to provide high overall performance, ruggedness and reliability.
The parts are rated for operation at a maximum junction temperature of 175°C, which further contributes to their long lifetime even in extreme conditions of use.
