EL SEGUNDO, CA, November 1996 - International Rectifier, the leading global supplier of semiconductors for power conversion applications, has developed a new surface mount package for Schottky diodes, the component of choice for most power output stages in power supplies, motor drives and lighting ballasts applications, to name a few.

This new surface mount package, designated the D61, has a 30 percent larger footprint than that of a standard D2PAK, but provides a thermal efficiency of 0.72 oC/W -- more than 2.4 times that of the D2PAK package. This means that a standard Schottky diode in the new D61 package can accommodate 2.7 times higher current than the same die in a D2PAK.

"Our new D61 package for Schottky diodes will really end up saving space for designers in many applications," said Bret Daniels, product marketing manager for Schottky diodes at International Rectifier. "Using the enhanced power handling capabilities of the new D61 package, engineers can easily replace two Schottky's in TO-227 packages or four devices in TO-220 D2 PAKs in their current designs with a single Schottky in a D61 package, and still provide the same current carrying capability."

The new D61 package measures 19.93 mm wide by 10.00 mm deep by 6.10 mm high. Designers can specify the D61 package for the entire range of IR Schottky diodes, with current ratings from 60 to 80 amps. .
