EL SEGUNDO, CA. May 2000 - International Rectifier (IR®) today introduced four new 12V and 20V P-channel HEXFET® power MOSFETs, which set new battery management and power conversion efficiency standards in the TSSOP-8 package. For example, the 12V IRF7701 is a MOSFET with 11 milliohms RDS(on) at 4.5V, 21 percent better than competing devices.

The lower RDS(on) contributes to higher power system efficiency, resulting in a longer operating life for portable, battery-operated equipment such as cell phones, digital cameras, notebook computers and other small electronic products. "Using IR's new IRF7701, IRF7702, IRF7750 and IRF7700 HEXFET® power MOSFETs in new or existing designs can lead to smaller and more efficient products," said Jorge Llorens, technical marketing manager for Portable Products at IR. "The addition of this new package style not only shows IR's commitment to the portable and mobile marketplace, but also allows IR to offer one of the broadest ranges of power MOSFET devices in the industry. This enables the designer to use a minimum footprint for the performance required."

The TSSOP-8 package is about 35 percent smaller than the industry-standard SO-8. IR's silicon technology makes the smaller TSSOP-8 devices perform as well as many of the larger SO-8-packaged devices.

In fact, the new 12V TSSOP-8 devices have guaranteed RDS(on) performance with a gate voltage of 1.8V. This efficiency guarantee helps designers to maximize battery life and to simplify circuits, since an additional boost circuit may not be required.

Samples and production quantities are available immediately. Pricing is US $0.95 each for the IRF702, and $1.08 each for the IRF7700, IRF7701 and IRF7750 in 10,000-unit quantities.

Data sheets for these components are available from the IR Web site (www.irf.com) and Fax-On-Demand system (310-252-7100 USA and +44 1883 783 420 Europe).
