Fairchild Accelerates Electric Vehicle Design with Auto Qualified SuperFET II MOSFETs & High Voltage Rectifiers

Fairchild broadens automotive portfolio while allowing higher rating designs with excellent performance that doesn’t trade off reliability

SAN JOSE, Calif. — (BUSINESS WIRE) — April 1, 2015Fairchild (NASDAQ: FCS), a leading global supplier of high-performance power semiconductor solutions, is addressing the advanced needs of automakers and their parts suppliers with new automotive qualified SuperFET® II MOSFET and High Voltage Rectifier product families, both of which enable cleaner and smarter vehicles overall and are ideal for increasing the power ratings of onboard chargers and DC-to-DC converters used in hybrid, plug-in hybrid and all-electric vehicles.

“A chief goal for plug-in hybrid and electric vehicle manufacturers is keeping on-board battery chargers and DC-DC converters as light and small as possible while increasing power levels,” said Fabio Necco, Director, Hybrid and Electric Vehicle Segment at Fairchild. “With the broad portfolio of new SuperFET II MOSFETs and High Voltage Rectifiers, Fairchild is enabling manufacturers to maximize efficiency, power density and reliability of these units, which is key to reducing their size and weight and is of course in line with the environmental, economic and energy benefits inherent in electric vehicle development.”

Fairchild’s AEC-Q101 qualified 650V SuperFET II MOSFET family is comprised of 9 devices in a wide range of package options and covering an industry-low 41 mOhm RDS(on), enabling customers to reduce both switching and conduction losses.

The 650V SuperFET® II MOSFET family is well suited for hybrid and plug-in electric vehicles as its low specific resistance and excellent switching performance enable high levels of efficiency. The new family uses the latest super-junction technology to enable both a small form factor and greater efficiency while its robust built-in diode at high dv/dt conditions can improve bridge circuit reliability.

Additionally, the 650V SuperFET II MOSFET family’s body-diode performance enables manufacturers to achieve superior switching performance with low electromagnetic interference (EMI). This is important as hybrid and plug-in electric vehicles are inherently ‘harsh’ EMI environments and adding as little additional EMI as possible is an advantage to improve the whole system reliability.

Rectifiers Up to 1000V Cover Automotive Power Market Spectrum

Complementing the 650V SuperFET II MOSFETs is Fairchild’s family of automotive High Voltage Rectifiers, which combine outstanding performance with automotive-level reliability. The family is qualified to meet the industry’s AEC-Q101 specification and available in a broad range of voltage and current ratings, which makes them ideal for the on-board chargers of plug-in hybrid and electric vehicles, as well as DC to DC converters, stationary chargers and other high-voltage powertrain applications.

This product family is currently divided into three technology platforms – Ultrafast, Hyperfast and STEALTHTM – that were designed considering the trade-offs between switching loss and conduction loss.

Ultrafast has the lowest VF (forward voltage), which makes it suitable for low switching frequency applications and applications without a strict EMI requirement. The Hyperfast devices have lower turn off time for faster switching applications such as PFC stages and secondary rectification stage of onboard charger.

Stealth rectifiers are faster than the Hyperfast and offer soft recovery to reduce noise and ringing at the cost of a somewhat higher VF (compared to Ultrafast) and higher reverse recovery charge Qrr (compared to Hyperfast). They are also suitable for high switch frequency applications with an EMI requirement, such as PFC.

Fairchild’s nine new automotive High Voltage Rectifiers are available with breakdown voltages of 600V and 1000V, forward currents from 15A to 80A and multiple package options, including TO247, TO220 and die sales (wafer, Tape &Reel and Known Good Die). With these new additions, Fairchild’s portfolio of automotive qualified rectifier is made up of 22 products. Fairchild can also customize these devices to suit manufacturers’ specific needs, such as custom dies and breakdown voltages.
