Vishay Intertechnology 1 A Fred Pt rectifiers

Vishay Intertechnology has introduced four 1 A FRED Pt ultrafast recovery rectifiers in the low-profile SMF eSMP series package. Combining fast and soft recovery characteristics with low leakage current and low forward voltage drop, the AEC-Q101-qualified VS-1EFH01WHM3, VS-1EFH01W-M3, VS-1EFH02W-M3 and VS-1EFH02WHM3 reduce switching losses and power dissipation in automotive and telecom applications.

The rectifiers offer reverse voltages of 100 and 200 V, reverse recovery times of 25 ns and forward voltage drop of 0.93 V. With compact footprints and low profiles of <1 mm, the SMF package is said to save PCB space compared with SMA, SMB and SMC packages while increasing power density.

The rectifiers are optimised for DC/DC converters in automotive engine control units, ABS and LED lighting, in addition to telecom DC/DC bricks. The devices feature a planar structure and platinum doped lifetime control to guarantee high overall performance and ruggedness. The components offer an operating junction temperature to 175°C.

The rectifiers provide an MSL moisture level of 1 per J-STD-020 and LF maximum peak of 260°C, meet the JESD 201 Class 2 whisker test and are RoHS-compliant and halogen-free. They are suitable for automated placement and allow for automated optical inspection in automotive systems.
