STMicroelectronics (STM - Snapshot Report) has announced an advanced version of its superjunction power Metal-Oxide-Semiconductor Field-Effect Transistors (MOSFETs), MDmesh II Plus™ Low gate charge (Qg) for consumer appliances, computing and telecom systems, lighting controllers and solar energy equipment.

The new device, MDmesh II Plus™ Low Qg, features low gate charge as well as low input, which helps in efficient switching without power loss. The device helps to save energy in resonant-type power supplies that are widely used in LCD TVs. Additionally, the device is highly stable in environments with significant voltage fluctuations, which saves transistors from sudden breakdown.

The superjunction MOSFETs have extremely fast switching characteristics and, therefore, reduce switching losses. The superjunction technology allows power transistors to combine small size and high voltage capacity to improve energy efficiency when turned on.

According to the Multimedia Research Group, the superjunction MOSFET market is expected to grow at 10.3% per year to $1 billion by 2018. Consumer remains the main application segment for superjunction MOSFET and accounts for two third of its total market. Currently, the superjunction MOSFET market stands at less than $5 million.

The superjunction MOSFET market will continue to expand steadily given increasing concerns about protecting the global environment. In the IT sector, green IT has been attracting attention as a way to achieve power savings. In order to reduce power loss in IT equipment, it is necessary to make the power converters used with IT equipment more efficient. Hence, there is a strong demand for energy-efficient MOSFETs. STMicro is therefore likely to be one of the beneficiaries of this growth.

STMicroelectronics is one of the pioneers in the field of high efficiency solutions with its superjunction power MOSFETs. The companyprovides cutting-edge solutions to meet the growing demand for high-performance devices with low voltage consumption in today's wireless telecommunications and consumer electronics applications.

In the recently concluded fourth quarter of fiscal 2012, the company’s total revenue of $2.16 billion was down 1.3% from the year-ago period. Net loss was 11 cents per share, wider than the Zacks Consensus Estimate of 9 cents loss per share on lower volumes and lower gross margins.

STMicroelectronics carries a Zacks Rank #4 (Sell). However, other semiconductor stocks that have been performing well and are worth considering include Intersil Corporation (ISIL - Snapshot Report), KLA-Tencor (KLAC - Analyst Report), and Qualcomm Inc. (QCOM - Analyst Report), all carrying a Zacks Rank #2 (Buy).
