EL SEGUNDO, CA. February 1999 - International Rectifier (IR^®) now offers a family of new Schottky diodes optimized specifically for OR'ing applications in high-reliability power supplies. Typified by the 40L15CW, these new diodes match competitive devices in all specifications, but add the advantage of 150°C maximum junction temperature at no extra cost. This higher temperature rating allows designers to use smaller heat sinks, saving space and money. Operating the device junction at a higher temperature allows a further reduction in forward voltage drop for even greater efficiency.

By selecting a proprietary barrier metal, IR is able to produce Schottky diodes with lower than average loss, coupled with high-reliability. The common cathode arrangement in these new diodes makes them suitable for use in systems with power levels of 20A when used in the common-cathode mode or 40A when the internal diodes are paralleled. Such levels are typically found in computer servers and small telecom system power supplies.

Other members of the new IR 'L' Series Schottky diodes include the 40L15CT and the 40L15CTS. These new devices offer similar performance to the 40L15CW die, but are packaged in a TO-220 and D2Pak, respectively, providing a tremendous space savings over the TO-247 package of the 40L15CW.

Samples can be located through International Rectifier's normal sales channels.
