EL SEGUNDO, CA. November 1998 - International Rectifier (IR() now offers two new package styles, the Super-220( and Super-D²Pak(, for their industry leading power semiconductors, expanding IR's leadership position in power packaging in terms of density, reliability and space savings. Both new package types feature the same footprint and lead spacing as industry standard packages, but accommodate far larger semiconductor die and therefore can handle much higher currents. These packages also perform to the toughest commercial reliability standards available.

"Designers are constantly looking for ways to improve the power density of their systems," says Chris Ambarian, director of technical marketing for MOSFETs and IGBTs at International Rectifier. "These packages help them reach their targets with minimal engineering effort, providing the required space savings while maintaining time to market. The increases in power density achieved also allow designers to realize cost savings by reducing the number of paralleled devices required for a particular circuit, significantly reducing costly board real estate."

"With the introduction of ever lower RDS(on) devices, packages are becoming a limiting factor in actual circuit performance. The increased current handling capability of both these new package styles allows our customers to better utilize the silicon potential, especially for higher current applications such as in low voltage battery motor drive and automotive applications. These packages also have inherently low inductance features that are excellent for these and power supply applications," Ambarian adds.

A new Super-220 has the same footprint as the TO-220, but is capable of housing over double the amount of silicon (equivalent to the industry standard TO-247). This device also features a current rating of 95A, 5A more than the standard TO-247 package and 20A more than the standard TO-220 package. Additionally, this versatile package can be clip mounted, or when the device is solder plated, surface mounted.

The Super-D²Pak has the same footprint as the industry standard D²Pak, but is capable of holding up to 40 percent more silicon, allowing for a considerable improvement in R_DS(on) for a given package outline. This device also has a 23 percent lower profile (>1mm) which makes it ideal for high density, space conscious systems. International Rectifier's industry standard D²Pak is rated at 75A, while the Super-D²Pak is rated at 95A.

Both packages will match the automotive standard of Q101 and 175^oC, which is regarded as the most stringent commercial standard available today. Samples can be located through International Rectifier's normal sales channels.
