Fairchild’s 800V SuperFET II MOSFET Family Delivers Lowest On-Resistance and Broad Package Range

By Editorial Team Last updated Feb 21, 2017

Fairchild (NASDAQ: FCS), a leading global supplier of high-performance power semiconductor solutions, today introduced its 800V SuperFET^® II MOSFET family, featuring broad package offerings and the industry’s lowest on-resistance (R_DS(ON)) and output capacitance (Coss). The new family enables designers to improve the efficiency, cost-effectiveness and reliability of high performance solutions requiring breakdown voltage higher than 600V / 650V, and also reduces the board space of these designs by enabling the elimination of components.

The best-in-class reliability of the 800V SuperFET II MOSFET family, coupled with its excellent efficiency and thermal characteristics, makes it ideal for a variety of applications. Meanwhile, its broad range of package options gives designers tremendous flexibility, particularly with size constrained designs. Key applications for the family include LED lighting, power supplies for LED televisions and home theater audio equipment, power adapters, servers, industrial power and auxiliary power supplies, as well as micro solar inverters.

“Manufacturers can improve the efficiency and reliability of their products with Fairchild’s new 800V SuperFET II MOSFET family, which is significantly more efficient than its closest competitor thanks to excellent switching performance and low specific resistance,” said Wonhwa Lee, principal technical marketing engineer at Fairchild. “The new family uses the latest super-junction technology to enable a small form factor with higher efficiency than ever before and its robust built-in diode at high dv/dt conditions can improve the reliability of industrial bridge circuits.”

Fairchild’s newest 800V SuperFET II MOSFET family is comprised of 26 devices covering a R_DS(ON) range of 4.3 Ohm to an industry low of 60 mOhm*, all offered in a wide range of standard package options, giving designers greater choice and flexibility in employing the best device for their specific application. For example, the FCD850N80Z, a key member of the family, combines an exceptionally low 850 mOhm R_DS(ON)(max) in DPAK with 6~11 percent lower R_DS(ON) (max) and 8~13 percent lower Coss (@400V) than its primary competitors, making it ideal for LED lighting applications which require low resistance and are size constrained.
