Various options provided for traction inverters and other motor drive components

Fairchild is currently expanding its portfolio of automotive-grade semiconductor solutions for hybrid electric vehicles (HEVs), plug-in hybrid electric vehicles (PHEVs), and electric vehicles (EVs) with new discrete and bare-die IGBTs and diodes. These IGBTs and diodes are suitable for traction inverters and key components in all HEVs, PHEVs, and EVs that convert direct current from battery power into the three-phase alternating current required for the vehicle's drive motors.

All of these new discrete and bare-die IGBTs and diodes utilize advanced field-stop 3rd generation IGBT technology and automotive-grade smooth, high-speed recovery diodes, and feature additional functions and options. Through this combination of technology, functions, and options, Fairchild can provide discrete and bare-die solutions with highly controlled characteristic distributions.


"The new disclete and bare-die IGBTs and diodes are attractive options for automotive manufacturers and their suppliers who require performance, reliability, and flexibility to build traction inverters best suited for specific requirements," said Sergio Fissore, Executive Vice President and General Manager of Fairchild’s Automotive Business Unit.
Fairchild's new FGY160T65SPD_F085 and FGY120T65SPD_F085 discrete IGBTs are optimized for traction inverters and other HEV/PHEV/EV electric vehicle components requiring high power density and high reliability.

Fabio Necco, Director of Fairchild’s H/EV Product Line, explained, “Additional improvements to robustness are being further tested in final tests, addressing the specific requirements of traction inverter applications and being applied to 100% of finished products. Along with a best-in-class 650V breakdown voltage, 50V higher than existing solutions, this additional step provides additional protection against electrical overloads.”

Complementing performance and stability is the flexibility provided by these discrete IGBTs, which allows designers to customize the product. At the same time, designers can achieve the required system rated capacity by simply adding IGBTs and improve the overall efficiency of the design of traction inverters or other electric drive components.
In addition, Fairchild announced that automotive manufacturers and automotive parts suppliers building their own power modules for high-performance traction inverters and other motor drive components can use Fairchild's PCGA200T65NF8, PCRKA20065F8, PCGA300T65DF8, and PCRKA30065F8 bare die IGBTs and diodes.

Bare die IGBTs feature monolithic current and temperature sensors, providing an enhanced level of protection. Bare die IGBTs can be customized to meet specific user requirements. Options include changing gate pad size and position to accommodate different aluminum wire diameters, adjusting die size, and customizing breakdown voltage and other electrical characteristics. A solderable top metal version is also available and is designed for advanced assembly techniques without wire connections, such as soldering and sintering.

Fairchild is expanding its portfolio with a new automotive-grade module currently under development. This module integrates IGBTs, freewheeling diodes, and gate drivers into a single electrically isolated package. Suitable for auxiliary motor control applications such as oil pumps and A/C compressors, it simplifies power design and assembly and improves EMI performance as the smallest solution on the market. The power module is currently being sampled and is expected to begin production in June.
