Vishay Intertechnology 1 A And 2 A FRED Pt® Ultrafast Rectifiers In SMP Package Increase Power Density, Improve Efficiency

Space-Saving 100 V and 200 V Devices Feature Compact 3.85 mm by 2.03 mm Footprint With Low 1 mm Profile

Malvern, PA (GLOBE NEWSWIRE) - Vishay Intertechnology, Inc. (NYSE: VSH) today expanded its offering of FRED Pt® Ultrafast recovery rectifiers with eight new 100 V and 200 V devices in the eSMP® series SMP (DO-220AA) package, including the industry’s first to offer current ratings to 2 A. Measuring 3.85 mm by 2.03 mm with a low 1 mm profile, the Vishay Semiconductors diodes provide space-saving alternatives to devices in the SMA (DO-214AC).

The 1 A and 2 A rectifiers released today increase power density by providing the high current ratings typically reserved for the SMA package in the smaller SMP, which utilizes 24 % less PCB space. For excellent thermal performance, the devices feature an asymmetric design with a large metal pad for heat dissipation, while their FRED Pt technology enables ultrafast recovery times down to 14 ns at TJ = 25 °C, reduced Qrr to 10 nC, and soft recovery features over the entire working temperature range of -55 °C to +175 °C.

Available in AEC-Q101 qualified versions, the rectifiers feature low forward voltage drop down to 0.69 V, which reduces power losses and improves efficiency in high frequency inverters, DC/DC converters, freewheeling diodes, and power factor correction in automotive engine control units (ECU), anti-lock braking systems (ABS), and HID and LED lighting, and telecom and industrial power supplies.

The devices offer an MSL moisture sensitivity level of 1, per J-STD-020, LF maximum peak of +260 °C. RoHS-compliant and halogen-free, the diodes are ideal for automated placement and allow for automated optical inspection (AOI) in automotive systems.
