A new family of rugged, high-efficiency power products from STMicroelectronics is set to enable technology companies to satisfy stricter power and efficiency targets set by eco-design standards and to target green energy applications such as solar micro-inverters, photovoltaic string inverters and electric vehicles.
The new devices include super-junction transistors (MOSFETs) capable of withstanding peak voltages up to 950 V, as well as 900 V devices offering best-in-class energy efficiency and 850 V devices offered in the ultra thin and space-saving PowerFLAT 8x8 HV package.
Super-junction technology enables MOSFETs to achieve higher operating voltages with very low electrical on-resistance in relation to device size, enabling power supplies to deliver increased system reliability and energy efficiency within compact overall dimensions.
The high voltage rating of the devices is an important benefit in HID lamp ballasts and other systems operating at AC line voltages and higher, such as solar micro-inverters and charging points for electric vehicles. In DC-to-AC inverters for solar micro-generators, high-efficiency, high-voltage MOSFETs enable designers to use higher switching frequencies and so generate high-quality AC power while reducing energy losses and solution size.
The new product range includes the 900 V STx21N90K5, 950 V STx20N95K5 and 950 V STx6N95K5 in various package options. The STL23N85K5 850 V variant in the PowerFLAT 8x8 HV high-voltage surface-mount package has a footprint of 64 mm², which is 56% smaller than the industry-standard D2PAK package. In addition, its mounted height of 1 mm is 77% lower than D2PAK, allowing use in ultra-slim designs.
