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.

New 160W High Power Density AC to DC Switching Mode Power Supplies from Gresham

The new series of HD160S high power density AC-DC power supplies pass mode was announced by Gresham Power Electronics.

The series HD160S proceed to 160W, approximately twice the power currently available in standard 51mm x 102mm footprint. The supplies are regarded as ideal for a low profile, 1U height, request that their height is only 27mm. The series uses the latest technology and design of switching topologies to deliver operational efficiency to 90% with a power density of more than 18W/in3, setting the standard low and midrange Power Products, says the company.

The single output power supplies offer output voltage of 5, 12, 24 and 48VDC. Other features include universal AC input (85 to 264VAC), Active Power Factor Correction (EN61000-3-2 Class D compliant) and protection against the temperature, more current and voltage. Safety Agency approvals, equipment, information technology (ATI), UL/cUL60950-1 / EN60950-1, Medical (UL / cUL 60601-1 / EN60601-1) and all models are CE-mark (DBT) and comply with the FCC / EN55022 Level B emission standards. The HD160S series offers reliable performance, high MTBF and is RoHS compliant.

Jake Moir, CEO of Gresham Power, said: "We are very pleased to offer our customers a high density Power Conversion in one of the smallest footprint in the industry. This will benefit our customers by reducing the space required to power conversion, which enable them to the functionality of their own products. "

The HD160S series is regarded as ideal for a wide range of applications, including bulk power front-end for distributed power architecture (DPA or IBA) in the telecom, industrial, military COTS, medical and scientific equipment.
