Digital Transistors Set Form Factor Benchmark

Assuming position as the smallest digital transistors on the market, the FJY families are rated at 200 mW and manage to squeeze a resistor bias network into their 1.7 mm x 0.98 mm x 0.78 mm SOT523F packages that take up just 2.8 mm² of board space. Target apps include cell phones, PDAs, handheld games, notebooks, and other portables. The NPN FJY30xx and PNP FJY40xx transistors meet the MSL 1 qualification for moisture-sensitivity levels and are offered in lead-free packages. They also meet or exceed the requirements of the joint IPC/JEDEC standard J-STD-020C and are compliant with European Union regulations. Price is $0.037each/1,000. FAIRCHILD SEMICONDUCTOR CORP.
