Philips Unveils MEGA Schottky Rectifier Diodes with Flat Lead Package

9/27/2004 - Royal Philips Electronics (NYSE: PHG, AEX: PHI) is helping mobile communications and consumer electronics manufacturers meet demand for smaller, more feature rich devices with the introduction of its portfolio of MEGA Schottky rectifier diodes. This is made possible by the small size and efficiency of Philips' new rectifiers in the compact flat lead SOD323F package. These rectifiers are more than 75 percent smaller than rectifiers in the industry standard SMA package and 60 percent more efficient than Philips' MEGA Schottky rectifiers in the SOD323. These rectifiers are ideal for use in power management applications to improve performance, to extend battery life and to reduce board space needed in products such as mobile phones and digital cameras.

Power dissipation due to forward voltage drop has remained a major limitation in improving overall electrical efficiency and reducing package size. The heat generated through power dissipation has caused package sizes to remain significantly larger than the silicon die to conduct heat away from the die and prevent damage to the device. Philips' compact SOD323F flat lead package has a shorter thermal pathway than the SOD323 gull wing package and uses thicker lead frame material to significantly 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.

"We live in a world where mobile communications and consumer products are growing at an exceptional rate. A good example of this is the digital still camera market with an annual growth rate of 30 percent (iSuppli, 2004)," said Achim Engelhardt, product marketing manager for diodes at Philips Semiconductors. "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."

Philips' SOD323F features a compact footprint of 1.7 x 1.25 x 0.7 mm. In addition to the performance benefits of the new package, the reduction of the package size provides cost savings in terms of purchasing and manufacturing - offering the optimum cost/performance ratio for Schottky rectifier technology.

Initial devices in Philips' portfolio of MEGA Schottky rectifier diodes in SOD323F are available now.
