Oct. 14, 2009 (Business Wire) -- Diodes Incorporated (Nasdaq: DIOD), a leading global manufacturer and supplier of high-quality application specific standard products within the broad discrete and analog semiconductor markets, has introduced high-current rectifiers with an ultra-low forward voltage (VF) drop. These rectifiers are targeted at power supply designers for use in consumer and industrial applications such as ultra-slim, end-user products, which include the following: laptop and netbook adapters, LED/LCD TVs, and telecom server power supplies where low profile height and efficiency are critical.
Diodes’ PDR5K is the industry’s first 5A/750V rectifier in a PowerDI®5 package. In a compact, low-profile solution, the PDR5K offers reduction in profile height up to 17 times compared to the height of the standard larger, bulkier bridge packages that are used in offline AC/DC Switch Mode Power Supplies (SMPS). The PowerDI®5 package has a low profile package height of just 1.15mm, offering the opportunity to reduce the total form factor of the end product. The PDR5K was designed in collaboration with Vicor Corporation of Andover, Massachusetts, a leading company in switched mode power supplies, to meet its power and space constraint application requirements.
“The introduction of the PDR5K extends Diodes’ leadership position as a company that is committed to working closely with customers to deliver new innovative products that meet the demands of the marketplace,” remarks Mark King, Diodes’ Senior Vice President of Sales and Marketing. “The PDR5K has already received very strong customer acceptance.”
In addition, Diodes is releasing a new family of 40A Ultra-low VF SBR® rectifiers in a low profile TO-262 package designed to be used as output rectifiers for SMPS devices. Using the Company’s patented SBR® technology, the SBR40U60CTE, SBR40U100CTE, and SBR40U120CTE offer ultra-low VF performance that reduces power loss for cooler operation and higher efficiency. The TO-262’s package height is 31.1% lower in profile height compared to a standard TO-220 package.
Combining both products in a single SMPS device, the PDR5K in the primary and the SBR40UxxxCTE as output rectifiers in flyback or forward converters on the secondary side, the total solution offers the lowest package profile height with the highest efficiency.
Both the PowerDI®5 and TO-262 packages are built using ‘green’ antimony and bromine-free mold compound that is RoHS compliant, underpinning Diode’s continual commitment to manufacturing environmental friendly products.
