Ultrafast recovery rectifiers

8 October 2014 Power Electronics / Power Management

Vishay introduced four new 1 A FRED Pt ultrafast recovery rectifiers in the SMF (DO-219AB) eSMP series package. Combining extremely 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 V (VS-1EFH01WHM3 and VS-1EFH01W-M3) and 200 V (VS-1EFH02W-M3 and VS-1EFH02WHM3), 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 saves significant PCB space compared with standard SMA, SMB and SMC packages, while increasing power density to lower overall costs.

The devices are optimised for DC/DC converters in automotive engine control units (ECU), ABS and LED lighting, in addition to telecom DC/DC bricks. They 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.
