First Schottky Diodes in PowerQFN Package

Less board space and profile height than D-PAK at same power

(PresseBox) (Heitersheim, ) Diotec Semiconductor announces the first Power Schottky diode in "Quad Flat No-leads" package, called PowerQFN 5x6. The device measures only 5 x 6 mm and has a profile height of as low as 1 mm. In contrastto common SMD power packages, the QFN outline comes without any exposed leads. The connection to theprinted circuit board is done with "integrated" leads on the bottom side of the package.
One big lead areaforms the diodes's cathode and allows for easy dissipating of the power losses. Two smaller lead pads canform a common anode or even two separated anodes for dual devices.

Offering the same power capability than D-PAK devices, the PowerQFN 5x6 needs only less than half of the boardspace of that outlines. And due to its low height, it isideally suited for low profile assemblies, e. g. on thebottom side of a PCB. The first device in this family is a 15 Amp / 40 Volt single Schottky diode and is named SK1540PQ. Typical applications include outputrectification of switch mode power supplies, reversepolarity protection and bypass diodes for solar modules. Further types will follow, including dual Schottky diodes and Standard to Ultrafast Recovery rectifiers.
