Fairchild Semiconductor's Highly Integrated Digital Transistors Offer Industry's Smallest Form Factor Packaging for Performance / Space Benefits in Portables

New FJY30xx and FJY40xx families add 29 new products to Fairchild’s broad transistor portfolio

March 22, 2007 − San Jose, California − Fairchild Semiconductor (NYSE: FCS) introduces two families of 200mW digital transistors that integrate an external resistor bias network into the smallest form factor package on the market. Tailored for use in switching, inverter, interface and driver circuits, the FJY30xx (NPN) and FJY40xx (PNP) series eliminate the need for an external resistor. This integration reduces part count, which in turn helps designers save board space, lower design costs, simplify circuit designs and maximize system performance. Board space is further optimized by utilizing surface-mount technology (SMT). Available in an ultra-small, ultra-thin (1.7mm x 0.98mm x 0.78mm) SOT523F package, these transistors feature the industry’s lowest package height compared to similar devices in SOT523 packaging while consuming only 2.8mm2 board footprint area. This combination of integration and packaging benefits makes Fairchild’s transistors ideal for use in cell phones, PDAs, handheld games, notebooks and other portable applications.

“Fairchild’s FJY30xx and FJY40xx digital transistors with built-in resistors offer designers the thinnest devices available for improving performance in designs limited by board-space and height requirements,” said Max Chua, product line manager, Digital Transistors. “Not only do these transistors lower part cost and ease design complexity, this new suite of 29 digital devices complements Fairchild’s existing line of transistors including the TO92-packaged FJN series, the SOT23-packaged FJV series, and the SOT323-packaged FJX series. This portfolio expansion provides designers with a comprehensive selection of 145 digital transistors from a tier-one supplier.”

Key features of the FJY30xx / FJY40xx transistors include:

• Built-in resistors reduce part count and simplify circuit design.
• Lowest (thinnest) maximum package height of 0.78mm (compared to similar devices at 1mm) meets height requirements of ultra-portable applications.
• Small foot print area (2.8mm˛) saves board space.
• Adds 29 new “boutique” and popular device types to existing portfolio for a total of 145 products.

These digital transistors meet the MSL 1 qualification for moisture-sensitivity levels. Offered in a lead (Pb)-free package, they also meet or exceed the requirements of the joint IPC/JEDEC standard J-STD-020C and are compliant with European Union regulations now in effect.
