Fairchild Expands IGBT Portfolio, Including New Standard Current Sense Ignition IGBT
Fairchild Semiconductor announced its FGB3040CS, which the company claims is the industry’s first standard current sense ignition IGBT. This IGBT is said to lower power dissipation by 30% and reduce heat in automotive applications by eliminating the need for a high current sense resistor. With the ability to sense current, the FGB3040CS is said to replace the high power sense resistor with a smaller, low current sense resistor, and to simplify system component requirements and total cost.
The FGB3040CS is designed with EcoSPARK® technology, offering what is claimed to be 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. The FGB3040CS also includes a Kelvin ground to improve current sense accuracy, and an elimination of the gate-to-emitter input resistor to simplify the IGBT gate control.
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 are said to offer tremendous advantages in applications that traditionally have not used these products in their designs. According to the company, 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 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 is said to reduce overall system cost compared to higher-rated ignition IGBTs.
The FGD2N40L, FGB3040CS and ISL9V2540S3S utilize lead-free (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 products are designed to meet the requirements of the European Union’s Directive on the restriction of the use of certain substances (RoHS).
Samples are available now, with an ARO of eight weeks. The products are priced (1000 pieces) as follows: FGD2N40L – $0.36; ISL9V2540S3S – $0.75; and FGB3040CS – $1.03.
