Vishay Intertechnology Inc. has rolled out four 1A FRED Pt Ultrafast recovery rectifiers in compact low-profile SMF (DO-219AB) eSMP series package. The devices combine extremely fast and soft recovery characteristics with low leakage current and low forward voltage drop, stated the company. In addition, the AEC-Q101-qualified VS-1EFH01WHM3, VS-1EFH01W-M3, VS-1EFH02W-M3 and VS-1EFH02WHM3 cut switching losses and power dissipation in automotive and telecom applications, Vishay added.

The Vishay Semiconductors FRED Pt rectifiers claim to offer reverse voltages of 100V (VS-1EFH01WHM3 and VS-1EFH01W-M3) and 200V (VS-1EFH02W-M3 and VS-1EFH02WHM3), reverse recovery times of 25ns, and forward voltage drop of 0.93V. With compact footprints and low profiles of < 1mm, the SMF package saves significant PCB space compared with standard SMA, SMB and SMC packages while increasing power density to lower overall costs, noted Vishay.

Ultrafast recovery rectifiers

The FRED Pt rectifiers are optimized for DC/DC converters in automotive engine control units (ECU), 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, ruggedness and reliability characteristics in these applications. The components offer an operating junction temperature to 175°C for a more robust design.

The VS-1EFH01WHM3, VS-1EFH01W-M3, VS-1EFH02W-M3 and VS-1EFH02WHM3 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. The rectifiers are geared 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 with lead times of eight weeks for larger orders.
