INTERNATIONAL RECTIFIER INTRODUCES NEW DUAL FETKY CO-PACKAGED DEVICE OFFERING 60% SPACE REDUCTION FOR COMPACT, HIGH EFFICIENCY POWER SYSTEMS TECHNOLOGY EDITORS EL SEGUNDO, CALIF.--(BUSINESS

--------------------------------------------------------------------------------

06:00 ET EL SEGUNDO, Calif.--(BUSINESS WIRE)--Sept. 12, 2002--International
Rectifier, IR(r) (NYSE:IRF.N), introduces the new IRF7335D1 Dual
FETKY(r) device, which co-packages two N-channel MOSFETs and a
Schottky diode in a single SO-14 package. The new device has the
highest current carrying capability among dual MOSFET-Schottky
co-packaged offerings today, and delivers 40% more current when
compared to IR's previously released IRF7901D1 device.
The IRF7335D1 offers as much as 60% space-savings compared to a
similar discrete circuit solution. The IRF7335D1 is designed for
standard 12V-input, 5V-, 3.3V- and 1.7V-output synchronous buck
converter circuits delivering up to 11A in notebook and desktop
computers, game consoles and Internet appliances. Co-packaging
simplifies layout, reduces packaging and assembly cost, increases
power density and simplifies procurement logistics.
The two MOSFETs in the IRF7335D1 are individually optimized for
control and synchronous switching functions. The synchronous MOSFET
has low on-resistance for reduced conduction losses. The control
MOSFET features low total gate charge and gate-to-drain charge for
reduced switching losses and is rated at 30V breakdown to safely
handle input voltage spikes. The internal Schottky diode has low
forward voltage drop for fast and efficient switching.
"The SO-14 package used for the new Dual FETKY device contains a
customized lead frame for improved thermal characteristics and
multiple die capability. In addition, the integration minimizes stray
package and PCB trace inductance between the synchronous FET and the
paralleled Schottky diode, simplifying board layout and increasing
efficiency," said Shawn O'Grady, Marketing Manager for Portable
Products at International Rectifier.
