en.Wedoany.com Reported - Vishay Intertechnology, Inc. announced the launch of 16 FRED Pt® ultra-fast recovery rectifiers using the new low-profile DFN6546A package. These 200 V rectifier devices feature a wettable flank design, with rated currents covering the range from 6 A to 15 A, and are available in commercial-grade and automotive-grade AEC-Q101 certified versions, suitable for space-saving and high-efficiency solutions in commercial, industrial, and automotive applications.
The DFN6546A package, as a new member of Vishay's Power DFN series, features a compact footprint of 6.5 mm x 4.6 mm and a typical height of 0.88 mm, contributing to optimized PCB space utilization. Through an improved copper design and chip layout, these rectifiers achieve good thermal performance, supporting higher current operation. Compared to 200 V components in SMPC (TO-277A) packages with the same footprint, these devices are 10% lower in height and offer a 50% higher rated current.
These single and dual devices can be used in applications such as high-frequency inverters, DC/DC converters, freewheeling diodes, load dump protection, clamp and snubber circuits, reverse and series polarity protection, and LED backlighting. In the automotive sector, they are suitable for engine control units (ECU), LED lighting systems, advanced driver assistance systems (ADAS), LiDAR and camera systems, as well as 48 V board nets, chargers, and battery management systems (BMS) in electric (EV) and hybrid electric vehicles (HEV). They also provide reliable performance in industrial automation equipment, energy harvesting, consumer electronics, computers, telecommunications, and medical devices.
The rectifiers offer low reverse leakage current, an operating temperature range of -55 °C to +175 °C, a low forward voltage drop of 0.75 V combined with fast reverse recovery time (trr) and low reverse recovery charge (Qrr), helping to reduce power losses and improve efficiency. The wettable flanks of the DFN6546A package support automated optical inspection (AOI), eliminating the need for X-ray inspection. The devices are suitable for automated placement, have an MSL moisture sensitivity level of 1, an LF maximum peak temperature of 260 °C, comply with RoHS standards and are halogen-free, with matte tin-plated leads that pass the JESD 201 class 2 whisker test.
Samples and production quantities of the new FRED Pt ultra-fast recovery rectifiers in the DFN6546A package are now available, with a lead time of eight weeks. Vishay Intertechnology, Inc., a Fortune 1000 company listed on the New York Stock Exchange (VSH), offers a broad portfolio of discrete semiconductors and passive electronic components, serving global automotive, industrial, computing, consumer, telecommunications, aerospace, and medical markets.
