New ultra-fast AEC-Q101-qualified recovery rectifiers for automotive and telecom systems

Vishay has introduced four new 1A and 2A 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 devices reduce switching losses and power dissipation in automotive and telecom applications. The VS-1EFH01HM3, VS-1EFH01-M3, VS-2EFH01HM3, and VS-2EFH01-M3 offer reverse voltages of 100V. The VS-1EFH02-M3 and VS-2EFH02-M3 provide reverse voltages of 200V, joining the previously released VS-1EFH02HM3 and VS-2EFH02HM3. The FRED Pt rectifiers feature reverse recovery times of 16 ns and typical forward voltage drop of 0.74V at 1A and 0.75V at 2A. With compact footprints and low profiles of < 1mm, the SMF saves significant PCB space compared with 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), anti-lock braking systems (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 +175C for a more robust design. The devices released today provide an MSL moisture level of one per J-STD-020, LF maximum peak of +260C, 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, says the company.
