FRED Pt rectifiers increase power density
Eight 100 and 200V devices have been added by Vishay Intertechnology to its FRED Pt Ultrafast recovery rectifiers series. The rectifiers are in the eSMP series SMP (DO-220AA) package, and are claimed to be the industry’s first to offer current ratings to 2.0A. The diodes measuring 3.85 x 2.03mm with a 1.0mm profile, and are offered as space-saving alternatives to devices in the SMA (DO-214AC).
The 1,0 and 2.0A rectifiers increase power density by providing the high current ratings typically reserved for the SMA package in the smaller SMP, which uses 24 per cent less PCB space. They have an asymmetric design with a large metal pad for heat dissipation, and the FRED Pt technology enables ultrafast recovery times down to 14 nanoseconds at junction temperature of 25 degrees C, reduced Qrr to 10nC, and soft recovery features over the temperature range of -55 to +175 degrees C.
The rectifiers are available in AEC-Q101 qualified versions and have low forward voltage drop down to 0.69V, 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 telecomms and industrial power supplies, explains Vishay.
The devices offer an MSL moisture sensitivity level of 1, per J-STD-020, LF maximum peak of +260 degreesC. RoHS-compliant and halogen-free. The diodes can be used in automated placement and allow for automated optical inspection (AOI) in automotive systems.
Samples and production quantities of the rectifiers are available now, with lead times of 20 weeks for large orders.
Vishay Intertechnology manufactures discrete semiconductors (diodes, MOSFETs, and infrared optoelectronics) and passive electronic components (resistors, inductors, and capacitors) for use in electronic equipment, in the industrial, computing, automotive, consumer, telecommunications, military, aerospace, power supplies, and medical markets.
