September 17, 2012, Seoul — STMicroelectronics (ST), a global semiconductor company providing a wide range of electronic applications, has launched SuperMESH™ 5, a new family of robust and highly efficient power MOSFETs. Because this new family can meet the stringent power and efficiency standards set by eco-design standards, it will help technology-based companies target the market for green energy-based applications such as solar micro-inverters, solar string inverters, and electric vehicles.

This product family includes the industry's first Superjunction transistor MOSFET capable of withstanding peak voltages up to 950V, a 900V device boasting superior energy efficiency, and the world's only 850V device available in an ultra-thin (space-saving) PowerFLAT 8x8 HV package. Superjunction technology MOSFETs can achieve high operating voltages with very low electrical on-resistance relative to device size, thereby improving both system reliability and energy efficiency during power supply.

With this, ST is not only a major supplier of Superjunction MOSFETs and the industry's only Tier 2 supplier of 900V Superjunction devices, but has also now become a provider of the highest voltage-rated devices in the industry. 800V devices are also scheduled to be added soon.

Superjunction technology realizing an eco-friendly world
To demonstrate the efficiency of the SuperMESH 5 device, ST has unveiled the first successful use case of the ultra-high voltage MOSFET. TCI ( www.tcisaronno.net ), an Italian solid-state lighting company, selected the 950V STU6N95K5, available in an IPAK package, to use as the main power switch for the latest LED driver for state-of-the-art multifunction LED lamps. Through this, remarkable energy efficiency could be achieved in a form factor with a smaller size and excellent cost-effectiveness. Maurizio Giudice, Marketing Director of ST’s Power Transistors division, said, “With ST’s next-generation SuperMESH 5 technology, TCI was able to achieve the best efficiency and sufficient margins in the market, which allowed us to make a very attractive offer to our customers.”

Other applications suitable for this new product family include flat-screen monitor TVs, PC power supplies, LED lighting drivers, and electronic ballasts for HID lamps. As the maximum power and minimum energy efficiency requirements demanded by eco-design standards, such as Energy Star and the EU’s Energy Product (ErP) regulations, become increasingly stringent, developers will be able to meet these requirements with these MOSFET products.

As an example of these increasingly stringent eco-design regulations, the recent Energy Star program requirement version 5.3 specifies that the absolute maximum power for flat-screen TVs larger than 50 inches must be limited to 108.0 watts. As another example, the EU’s ErP lighting regulation requires that minimum efficiency values for various HID lamp types be increased between 2012 and 2017.

The high voltage ratings of this Superjunction MOSFET family enhance system safety and reliability. This feature provides a significant advantage for operating systems at or above AC line voltage, such as HID lamp ballasts, solar microinverters, and charging points for electric vehicles. Achieving the minimization of charging time and vehicle operating costs at charging points requires a very high level of power conversion efficiency. Developers can utilize higher switching frequencies on DC/AC inverters for solar microgenerators with high-efficiency high-voltage MOSFETs, thereby producing high-quality AC power while reducing energy loss and the size of the solution itself.

Key Features of SuperMESH™ 5 MOSFET
The first products released in ST's 5th generation SuperMESH™ Superjunction family include the 900V STx21N90K5, 950V STx20N95K5, and 950V STx6N95K5, available in various package options. The STL23N85K5 850V variant in the PowerFLAT 8x8 HV high-voltage surface mount package achieves a 64 mm² footprint, which is 56% smaller than the industry-standard D2PAK package. Additionally, with a mount height of 1 mm, which is 77% lower than the D2PAK, ultra-slim designs are possible.
For the 900V STP21N90K5, the Performance Index (FOM), which shows overall energy efficiency when on and off, was 62.5%, which was found to be superior to competing products. Developers who choose the STP21N90K5 will be able to achieve this excellent increase in efficiency.
