1A and 2 A FRED Pt Ultrafast Rectifiers in SMP Package Increase Power Density, Improve Efficiency

Vishay Intertechnology added eight new devices in its FRED Pt Ultrafast recovery rectifiers in SMP(DO-220AA) packages. The new eight 100 V and 200 V devices feature compact 3.85 mm by 2.03 mm Footprint with low 1 mm profile which provide space-saving alternatives to devices in the SMA (DO-214AC).  The 1A and 2A FRED Pt Ultrafast rectifiers efficiently increases power density by providing the high current ratings typically reserved for the SMA package in the smaller SMP, which utilizes 24% less PCB space.

 

All eight devices in FRED Pt Ultrafast recovery rectifiers are AEC-Q101 qualified and feature low forward voltage drop down to 0.69 V helping it to reduce 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 rectifiers offer an MSL moisture sensitivity level of 1, per J-STD-020, LF maximum peak of +260 °C. For excellent thermal performance, the rectifiers 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. All the devices are RoHS-compliant and halogen-free and are ideal for automated placement and allow for automated optical inspection (AOI) in automotive systems.
