Vishay - New Launch Rectifier with Performance Improvements

A new 600V FRED Pt Hyper Fast Rectifier tandem is unveiled by Panasonic. The device reduces the loss of high-efficiency DC mode (CCM) for correcting the power factor (PFC) applications with extremely fast reverse recovery time, low forward voltage drop and low temperature resistance package.

The 8S2TH06I-M is optimized for use in desktop PCs, servers and power supplies for telecommunications, UPS systems, large-screen plasma and LCD power supplies, industrial power supplies, inverters and solar energy.

Balance single 'A' of the conduction and switching performance improvements, the 8S2TH06I-M to provide an overall reduction of the average power of 22% in typical applications of high frequency PFC.

Who has a reverse recovery time of the 11nS, the 8S2TH06I-M combines its Hyper-Fast switching performance with a rating of low forward voltage drop of 2.1V at 8A, the device to operate at higher frequencies to increase overall efficiency of the system. Her 2-pin TO-220 makes the device 8Adc provide a temperature of 120C in cases when an optimal insulation to 2 kV. The ceramic isolated TO-220 package is designed for easy installation with non-isolated units, but with a minimal effect on the benchmark thermal resistance of 2.3c / W junction to case.

Reverse recovery scheme for 8S2TH06I-M 7nC to 35nC at 25C and 125c, which significantly improve the arbitration between QRR and voltage drop represents. The result is the ability to combine operations with high frequency with lower losses, heatsinks and passive components makes it possible to restructure. Also, the M-8S2TH06I operating junction temperature of 175C make designs more robust and cost-effective and represents an improvement of 15% over competing devices, where the maximum is 150C, the company said.

Vishay - Power MOSFET N-Channel SiE876DF Device Power Control Circuits

A power MOSFET with the industry at the lowest resistance for a 60V device in a package with double-sided cooling is released by Vishay. The SiE876DF news, which comes in an SO-8 format PolarPAK package offers maximum resistance of 6.1 milliohms at 10V gate drive, an improvement of 13% in the next device gives the best comparable market society.

The n-channel SiE876DF is for the supply of industrial type power control circuits of motors, AC / DC for the servers and routers, and systems that use point of load (POL) Power Conversion. It is likely to be used as a switch on the primary side or secondary side rectification in higher education conversion of the intermediate bus voltage (CBI) designs.

In each of these applications the low resistance SiE876DF result in lower conduction losses and thus save energy. Besides the low conduction losses, which are TrenchFET silicon, double the cooling by the PolarPAK package enables better thermal performance for high current applications. This makes cooperation with a lower junction temperature. The lead frame PolarPAK based, encapsulated design also offers increased protection and reliability, in addition to simplification of production, because death is not exposed. The device has the same format as the other PolarPAK devices with drain-source voltage of less than 150 V, thus simplifying the PCB design. The SiE876DF is 100% Rg and UIS tested.

Samples and production 60V SiE876DF available, with lead times of 10 to 12 weeks for large orders, the company said.

1A Protected High-Side Load Switch in Compact TSC75

Expanding its family of the current limit of tax and the introduction of a new high of protection device has been announced by Vishay. The load switch can operate under a supply voltage range of 2.4V to 5.5V and a handful exit 1A.

The SiP4613A / B is designed for switching applications, including charging the battery switching, USB peripheral ports, hot swap, and other uses of power in laptops, PDAs, laptops and other electronic devices.

A defining the par l'utilisateur limiter le niveau actuel protégé l'entrée de tension d'alimentation de la charge excessive des courants qui peuvent causer une défaillance du système. To report a fault current CL pin will be low when the device is used in a limited state. In the stop mode, SiP4613A / B reduces the supply current to less than 1μA.

In addition to the current limit, the SiP4613A / B is protected by undervoltage lockout period and thermal shutdown. The temperature protection circuit prevents thermal runaway by turning off the switch at the intersection of the chip temperature reaches 165 C and the temperature falls below 145 C.

The opportunity to selectively turn on and shut down various system functions, and can switch between sources of supply, there are two versions of the diet. The SiP4613A has a low, so that input, while SiP4613B a high input. Available in lead (Pb)-free 6-pin package PowerPak TSC75-6, the device operates within the temperature range of-40C to +85 C, says the company.

IHLP Inductors is Now Available on the Vishay web site

One of the first free web-based tool that calculates the switching losses for IHLP inductors is now available on the website of Vishay. The user switching loss calculator is adapted for individual applications, so that designers and select the right part for an optimized board, while the acceleration of the market. The loss switching calculator is available for money, encourage and Buck / DC-DC converter topologies strengthen.

For the calculation of the inductance losses in the past, designers was to the complex equation by hand Steinmetz, a long process that increases the risk of human error. With the loss calculator designers just in the input and output voltage, frequency, output current, and temperature for its application. With the selection of an inductance value, ranging from 0.1μH to 10μH, the calculator provides immediate results for copper, core and total losses with rising temperature of the estimated inducer. The good Vishay IHLP room number is also displayed for the designer of the reference.

The calculator is usable for all applications IHLP inducer, including the Voltage Regulator Module (VRM) and DC-to-DC converter applications in end products, such as next generation mobile phones, laptops, desktops, servers, graphic cards, video games , Portable navigation systems, personal multimedia devices, systems and low-profile, high current power supplies and point of load (POL) converters, distributed energy systems, and field programmable gate (FPGA), says the company.
