Vishay Intertechnology Inc. recently introduced four new 1 A and 2 A FRED Pt® ultra-fast 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 Vishay Semiconductors VS-1EFH01HM3, VS-1EFH01-M3, VS-2EFH01HM3, and VS-2EFH01-M3 offer reverse voltages of 100 V. The VS-1EFH02-M3 and VS-2EFH02-M3 provide reverse voltages of 200 V, 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 0.74 V at 1 A and 0.75 V at 2 A. With compact footprints and low profiles of < 1 mm, 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 +175 °C for a more robust design.
The devices released today 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. Samples and production quantities of the new FRED Pt rectifiers are available now, with lead times of eight weeks for larger orders. Pricing for U.S. delivery only starts at $0.10 for the 1 A rectifier and at $0.12 for the 2 A rectifier.
