Silicon Carbide power MOSFETs from TT Electronics operate in environmentally challenged applications

TT Electronics, a global provider of engineered electronics for performance critical applications, today launched a Silicon Carbide (SiC) power MOSFET that is designed for high temperature, power efficiency applications with a maximum junction temperature of +225°C. As a result of this operating potential, the package has a higher ambient temperature capability and can therefore be used in applications, including distribution control systems with greater environmental challenges, such as those in close proximity to a combustion engine.

Supplied in a high power dissipation, low thermal resistance, fully hermetic, ceramic SMD1 package the 25A, 650V rated SML25SCM650N2B also ensures faster switching and low switching losses in comparison to normal Si type MOSFETs, consequently the size of the passive components in the circuit can be reduced resulting in weight and space saving benefits. The N-channel MOSFET features a total power dissipation of 90W at a T_J temperature of 25 degrees. A range of screening options are available.

For use in applications that require faster switching in high temperature power conversion topologies and systems, the SML25SCM650N2B will find favour with design engineers working in industrial power conversion applications including oil drilling, distributed management control systems, renewable energy applications / power conversion, space systems and applications.

Silicon Carbide is the new semiconductor technology of choice to help power electronic design engineers design with more efficiency, with higher operating temperatures to lay the foundation for future conversion and control system design demands.  With the SML25SCM650N2B, the combination of new Silicon Carbide technology with a high reliability, industry standard outline hermetic packaging technology coupled with TT Electronics’ renowned Lutterworth based design and manufacturing capability delivers value and very high performance to the end customer.
