NXP Semiconductors has released the SOD123W and SOD128 MEGA Schottky rectifiers housed in FlatPower packages.

With the packages' clip bond technology, the devices deliver high-power capability comparable to standard SMA packages. Boosting the low forward voltage-drop, the new types allow a high peak current of more than 50A and achieve power dissipation Ptot up to 1W.

In addition, the height of both packages is reduced by 50 percent compared to SMA packages, enabling much smaller designs. The SOD123W supports this trend with a body size of 2.6mm x 1.7mm x 1mm while the SOD128's dimensions are 3.8mm x 2.5mm x 1mm. Both packages are footprint-compatible to SMA and SMB packages, providing an ideal solution for a 1:1 replacement.

"The market is increasingly demanding thinner and more powerful devices. With the new FlatPower packages, NXP has developed a technology that enables smaller designs, delivers high performance and still enables the lowest forward voltage-dropwhich is crucial especially for battery-driven systems," said Wolfgang Bindke, product marketing manager for diodes, NXP.

The MEGA Schottky rectifiers are designed for a broad range of low-voltage and mobile applications including power management circuits, DC/DC converters, step down and synchronous converters, and free-wheeling diodes for inductive load in motors and relays. Qualified to the rigorous AEC-Q101 standard, the new FlatPower diodes can be used for automotive and industrial applications.

The SOD123W and SOD128 MEGA Schottkys also meet the environmental protection targets. The plastic is free of halogens and antimony oxides and complies with non-flammability classification UL 94V-0 and RoHS standards.

Six 30V and 40V low VF types in the new FlatPower packages are released and ready for production. Samples are available immediately for design-in.

Another six 20V and 30V low VF types will be released in Q1 09. An additional 15 types with up to 60V and low VF are in development for release in Q3 09.

The prices for the final series with 26 types will range from $5 to $9 for 100-unit quantities.
