Fairchild Semiconductor’s FGB3040CS is said to be the industry’s first standard current sense ignition IGBT. This IGBT lowers power dissipation by 30 percent and reduces heat in automotive applications by eliminating the need for a high current sense resistor. With the ability to sense current, the FGB3040CS replaces the high power sense resistor with a smaller, low current sense resistor, simplifying system component requirements and total cost. The FGB3040CS is designed with EcoSPARK technology, offering the highest energy density for ignition IGBTs in the industry. This technology enables a die size that is small enough to fit into a D-Pak without giving up performance.

Fairchild has further expanded its IGBT portfolio with two new products, the FGD2N40L and the ISL9V2540S3S. The FGD2N40L is an ignition IGBT for small engine applications, such as lawn mowers and snow blowers. These IGBT devices offer tremendous advantages in applications that traditionally have not used these products in their designs. Traditional bi-polar technologies need base current to activate the spark, which requires a higher engine RPM for the ignition system to start. Since the gate of Fairchild’s IGBT has extremely high impedance, it requires less energy to control the spark, allowing operation at lower engine RPMs. The ISL9V2540S3S is an ignition IGBT for designs requiring 250mj of SCIS capability. It reduces overall system cost compared to higher-rated ignition IGBTs.

Fairchild’s unique capabilities in advanced process and packaging technologies, as well as its ability to integrate power analog, power discrete and optoelectronic functionality into innovative packaging, enable Fairchild to develop energy efficient solutions for the automotive electronics market. Fairchild offers the industry’s most comprehensive portfolio of products, from 1W to >1200W, to maximize energy efficiency in today’s automotive electronic applications such as power management, body control, motor control, ignition and engine management, and electric and hybrid electric vehicle systems.
