August 30, 2006–South Portland, Maine–Fairchild Semiconductor (NYSE: FCS) has developed a family of low on-resistance 600V SuperFET™ MOSFETs specifically to address the DPAK (TO-252) device requirements of the latest ultra-slim, low-profile ballast applications. To minimize switching and conduction losses and meet system efficiency needs of these fast-switching lighting designs, Fairchild’s DPAK SuperFETs offer as little as one-third the on-resistance (0.6 ~ 1.2 Ohms) of traditional planar MOSFETs. They also have the ability to withstand both high-speed voltage (dv/dt)- and current (di/dt)-switching transients necessary for ballasts to operate reliably at very high frequencies.

Typically, as the breakdown voltage of a standard MOSFET rises, its R_DS(on) also goes up exponentially and leads to increased die size. Fairchild’s proprietary SuperFET technology changes this R_DS(on)-to-die size relationship from an exponential to a linear one. This approach allows SuperFET devices to achieve a very impressive R_DS(on) and small die size, even at a 600V breakdown voltage. Fairchild’s SuperFET in DPAK is the latest evolution of this packaging innovation.

“We’ve added DPAK devices to our SuperFET product portfolio specifically to meet the energy efficiency and the space-reduction demands of lighting manufacturers,” said Taehoon Kim, vice president of Fairchild Semiconductor’s Functional Power Group. “Our proprietary SuperFET technology results in the extremely low on-resistance needed to decrease MOSFET die-size and make 600V/0.6 Ohm DPAK-packaged product possible. In comparison, typical 600V/0.6 Ohm planar MOSFET devices for lighting applications come in larger TO-220- or D²PAK packages. Fairchild’s DPAK SuperFET technology offers our customers low on-resistance devices in more compact packaging, therefore addressing the growing market trend calling for slimmer electronic ballasts.”

In addition to DPAK-packaged devices for ballasts, Fairchild offers a full portfolio of SuperFET products for lighting, active Power Factor Correction (PFC) and AC/DC power-supply systems. For more information about the SuperFET portfolio, please go to www.fairchildsemi.com/superfet.

Fairchild offers an array of products for a total lighting solution. In addition to SuperFET devices, these products include PFC controllers, ballast control ICs and high-voltage gate drivers.

SuperFET MOSFETs are available in a lead (Pb)-free DPAK package that meets or exceeds the requirements of the joint IPC/JEDEC standard J-STD-020C and is compliant with European Union regulations now in effect.
