The discrete and bare die IGBTs and diodes use third generation Field Stop Trench IGBT technology and a soft fast recovery diode qualified to automotive grade standards. The combination of these features is said to result in a tight parametric distribution.
Fairchild’s FGY160T65SPD_F085 and FGY120T65SPD_F085 discrete IGBTs are suited to traction inverters and other hybrid/electric vehilce powertrain components that require high power density and high reliability.
“An additional enhancement is extra screening at final testing that addresses the specific needs of traction inverters applications and is applied to 100% finished goods,” explained Fabio Necco, director of Fairchild’s H/EV product line. “Along with a 650V breakdown voltage, which is 50V more than existing solutions, this extra step provides further protection against electrical overstress.”
Designers can also add IGBTs in parallel to achieve the required system power rating, while also improving the overall efficiency of their traction inverter or other powertrain component designs.
Fairchild is also making bare die IGBTs and diodes available to those companies building their own power modules for high performance traction inverters and other motor driving components.
Bare die IGBTs are available with integrated monolithic current sense and temperature sense to provide additional levels of protection. They
can also be customised, with options including gate pad size and location, die resizing and customising the breakdown voltage and other electrical parameters. A solderable top metal version is designed for advanced wire bondless assembly technologies.
Meanwhile, an automotive grade module in development integrates IGBTs, freewheeling diodes and gate drivers in one electrically isolated package. The device, likely to be aimed at auxiliary motor control applications, is believed to be the smallest such solution. Sampling now, the module is scheduled to be available in production quantities in June 2016.
