Vishay Intertechnology introduced four new 1 A FRED Pt® Ultrafast recovery rectifiers in the compact, low-profile 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 Vishay Semiconductors FRED Pt rectifiers released today 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 saves significant PCB space compared to standard SMA, SMB, and SMC packages, while increasing power density to lower overall costs.
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, LF maximum peak of +260 °C, meet the JESD 201 Class 2 whisker test, and are RoHS-compliant and halogen-free. The rectifiers are ideal for automated placement and allow for automated optical inspection (AOI) in automotive systems.
