Diodes Inc. (Westlake Village, CA ) announced the launch of the anticipated Powermite3 product line with the introduction of the SBM1040 schottky barrier rectifier. The new devices provide significant low-leakage and space-savings advantages over larger and higher profile DPAK technology, according to the company.
The high-efficiency rectifier offers ultra-low leakage current performance giving 100µA (typical) and 300µA (maximum) at a VR of 35V, and a TS of 25 degrees C with 1.25mA (typical) and 25mA (maximum) at a VR of 35V and a TS of 100 degrees C. The resulting IR increases the overall efficiency and enables the SBM1040 to be stable under high-temperature operation. In addition to the Powermite3, Diodes is also introducing a version of the schottky barrier rectifier in the industry-standard DPAK.
The Powermite3 package measures 1.1mm in height and offers a reduction in footprint size, occupying only 33mmsq. The compact profile and smaller footprint is of primary importance where circuit board space is at a premium, making the package suitable for use in dc/dc converters, switch-mode power supplies, notebook PCs, graphics cards, and hand-held and portable electronics.
Diodes is preparing to offer multiple new schottky rectifier products based on the Powermite3 package during 2002. The rectifiers will cover a range of values from 3A to 10A for current ratings and 30V to 100V for breakdown voltages.
