Thermal resistance is of great interest to electronic engineers, since most sensitive electrical components generate heat and need to be cooled. Allowing heat to flow can be crucial for civilian missions as well as security, HLS and military missions. Electronic components malfunction or fail if they overheat, and some parts routinely need measures taken in the design stage to prevent this

Finding a solution which addresses issues affecting thermal performance can help lower system costs through enhanced performance and reduced cooling materials. Among the advantages: power transistors are ideal for industrial and broadcast applications including CO₂ lasers, plasma generation equipment, MRI amplifiers and particle accelerators, as well as FM and VHF broadcast transmitters.

Freescale Semiconductor [NYSE: FSL], the global leader in radio frequency (RF) power transistors introduced the industry’s highest power RF power transistors housed in plastic packaging. The new MRFE6VP61K25N delivers power in excess of 1250 W CW, and the new MRFE6VP6600N delivers power in excess of 600W.

Freescale expands its rugged RF portfolio with breakthrough high power plastic packaged transistors. An industry expert observed that the new CW 1250 W and 600 W plastic-housed products for industrial applications deliver market-leading thermal performance.

Freescale’s plastic packaging enables compatibility with mass volume soldering processes, enables tighter dimensional tolerances and provides a 30 percent reduction in thermal resistance compared to ceramic-packaged transistors.

“These new products continue Freescale’s long track record of delivering critical RF innovation for the industrial space,” said Paul Hart, senior vice president and general manager for Freescale’s RF business. “Providing the advantages of plastic packaging without compromising RF performance is a major leap forward that our customers can use to develop end-products that differentiate and win in competitive industrial markets.”

In addition to the ultra-high performance of these new devices, Freescale also offers a range of extremely rugged transistors designed to thrive in harsh industrial environments from 1 to 600 MHz. With today’s introductions, Freescale’ industrial portfolio now comprises five parts in ceramic and five parts in plastic, addressing power requirements ranging from 25 W to 1250 W.
