– March 17, 2015 — Fairchild (NASDAQ: FCS), a leading global supplier of high-performance power semiconductor solutions, today introduced extended temperature (ET) mid-voltage MOSFETs that can operate at 175°C, 25°C higher than previous models, enabling manufacturers to improve product reliability and performance. Compared to industry-standard 150°C MOSFETs, these products deliver up to 85 percent higher power density and three times higher reliability.

This new family of ET MOSFETs meets the IPC-9592 power conversion standard, which means their maximum junction temperature can reach 150°C, compared to 125°C for standard 150°C MOSFETs, providing greater design margins. The 19 new devices are available in standard 5 mm x 6 mm and 3 mm x 3 mm packages, as well as the new TO-LL (TO-Leadless) package. These devices are available in a wide variety of voltage ratings including 30V, 40V, 60V, 80V, 100V, 120V and 150V.

Fairchild's ET MOSFET family, which offers an outstanding combination of superior heat resistance, higher power density and improved reliability, is ideal for DC-DC power supplies, AC-DC power supplies and motor drives used in a wide range of applications including avionics, micro solar inverters, power tools and communications.

“These latest additions to Fairchild’s extensive line of iFET MOSFETs provide designers with greater ‘headroom’ in their product designs to handle higher temperatures without relying on heat sinks or other methods of heat dissipation that add cost and complexity to their products,” said Suman Narayan, vice president of iFET products at Fairchild. “These new devices continue Fairchild’s tradition of providing designers with solutions that provide significantly greater design margin over competitive offerings.”

Capable of operating at 175°C, these new ET MOSFETs are particularly suited for applications that require high temperature operation, such as solar power generation and power-over-Ethernet (POE) applications. Additionally, this new product offers extremely high reliability and can be used in harsh environments, including those in avionics, railways and power tools.

In addition to operating over a wide temperature range, the high power density in a small package gives manufacturers greater flexibility during product design, allowing designers to reduce product size while maintaining the same output, or increase output without increasing size.
