Small is in. And this mantra has never been more evident in mobile communications and consumer electronics applications.

To help manufacturers of these applications meet the demand for smaller, more feature rich devices, Royal Philips Electronics has released its portfolio of MEGA Schottky rectifier diodes.

According to Philips, the new rectifiers in the flat lead SOD323F package are more than 75 percent smaller than rectifiers in the industry standard SMA package and 60 percent more efficient than its MEGA Schottky rectifiers in the SOD323 package.

The compact SOD323F flat lead package has a shorter thermal pathway than the SOD323 gull wing package and uses thicker lead frame material to lower the thermal resistance of the package. As a result, MEGA Schottky rectifiers in the SOD323F have a 50 percent higher current capability and operate at higher temperatures than other Schottky rectifiers, providing design engineers with increased flexibility in design in addition to board space reduction, the company said.

"The [Philips'] new portfolio of MEGA Schottky rectifiers combines the SOD323F package with Philips' MEGA Schottky rectifier technology to allow engineers to support this market demand with smaller designs that have a longer battery life," said Achim Engelhardt, product marketing manager for diodes at Philips.

Offers a compact footprint

Featuring a footprint of 1.7-by-1.25-by-0.7mm, the new rectifiers are suitable for use in power management applications to improve performance, extend battery life and reduce board space needed in portable products such as mobile phones and digital cameras. In addition to the performance benefits of the new package, the reduction of the package size provides cost savings in terms of purchasing and manufacturingoffering the optimum cost/performance ratio for Schottky rectifier technology, Philips said.
