Fast recovery rectifiers are low-profile for vehicle use
Four 1A FRED Pt ultrafast recovery rectifiers in the compact low-profile SMF (DO-219AB) eSMP series package reduce switching losses and power dissipation in automotive and telecomms applications. The VS-1EFH01WHM3, VS-1EFH01W-M3, VS-1EFH02W-M3, and VS-1EFH02WHM3 from Vishay Semiconductors have low leakage current and low forward voltage drop, and are AEC-Q101-qualified. Reverse recovery time is 25ns, and forward voltage drop is 0.93V. The SMF package measures 1mm and is claimed to save significant PCB space compared with standard SMA, SMB, and SMC packages while increasing power density to lower overall costs. The rectifiers are optimised for DC/DC converters in automotive engine control units (ECU), ABS, and LED lighting, in addition to telecomms 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. All 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 suitable for automated placement and allow for automated optical inspection (AOI) in automotive systems.
