Ignition IGBT cuts power dissipation by 30 percent

Fairchild Semiconductor says the FGB3040C is 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, which simplifies system component requirements and total cost, said Fairchild. The FGB3040CS is designed with EcoSPARK technology, which is said to enable 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, said the company.

Fairchild has also expanded its IGBT portfolio with the introduction of the FGD2N40L and ISL9V2540S3S products. The FGD2N40L is an ignition IGBT for small engine applications such as lawn mowers and snow blowers, while the ISL9V2540S3S ignition IGBT targets designs that require 250mj of SCIS capability. It reduces overall system cost compared to higher-rated ignition IGBTs, said Fairchild.

The FGD2N40L, FGB3040CS and ISL9V2540S3S use Pb-free terminals and have been characterized for moisture sensitivity in accordance with the Pb-free reflow requirements of the joint IPC/JEDEC standard J-STD-020. The devices are also RoHS compliant.

The FGD2N40L is priced at 36 cents, the ISL9V2540S3S at 75 cents and the FGB3040CS at $1.03, in quantities of 1,000. Samples are available now. Delivery is 10 weeks ARO.
