Fairchild Introduces Bipolar Junction Transistors For Electronic Ballast, Power Supply & Industrial Designs

Fairchild Semiconductor introduced its 3A and 5A bipolar junction transistors (BJT), which are said to contribute to energy-savings in electronic ballast, power supply and industrial designs due to what is described as their ultra-fast switching speeds and low saturation voltage.

The FJD5555’s saturation voltage is as low as 0.5V and the FJD5553 is as low as 0.23V which is said to be 50% lower than industry alternatives. The combination of low saturation voltage and high switching speed positively contributes to overall efficiency. Both the FDJ5555 and the FDJ5553 feature a high breakdown voltage (1050V), which is said to be particularly important for lighting applications that need a wide safe operating area. These transistors are packaged in compact DPAK packaging (64mm²) to conserve space in electronic ballast and power supply designs.

"The conservation of energy and the development of energy-efficient solutions is one of the most critical challenges facing the world today. Fairchild’s bipolar transistors offer an energy and space efficient solution for electronic ballast and power supply designs," said Thomas Teng, BJT Product Line Marketing Manager.

The FJD5555 and FJD5553 utilize lead-free (Pb-free) terminals and have been characterized for moisture sensitivity in accordance with the Pb-free reflow requirements of the joint IPC/JEDEC standard J-STD-020. The products are designed to meet the requirements of the European Union’s Directive on the restriction of the use of certain substances (RoHS).

The units have an ARO of 8 to 10 weeks, and are priced (each, 1000 pieces) as follows: FJD5553 – US $0.352; FJD5555 – US $0.41.
