ON Semiconductor has announced the expansion of its discrete packaging portfolio with new micro-packaged transistors and diodes. The new additions broaden the company's micro-packaged portfolio of transistors and diodes targeted to meet the needs of today's most demanding space-constrained portable applications.

"Small size and low profile while maintaining power density are critical parameters for our portable product customers," said Mamoon Rashid, VP and general manager of ON Semiconductor discrete products division. "ON Semiconductor offers micro-packaged diodes and transistors for power management, switching and protection applications to enable expanded feature integration in their portable productswithout increasing the size of their end-products or reducing power efficiency."

Micro-packaged transistors
ON Semiconductor now offers general purpose and bias resistor transistors (BRT) in SOT-723, SOT-963 and in SOT-1123 packages, measuring1.0mm x 0.6mm x 0.37mm. According to the company, the smaller, low-profile packages allow design engineers to use them in such applications as mobile handsets. The dual and complimentary micro-packaged transistors are lead-free and halogen-free. Budgetary pricing ranges from $0.06 to $0.08 per unit in 8,000 quantities.

Micro-packaged diodes
ON Semiconductor has expanded its SOD-923 NSR Schottky diode portfolio with higher current capability of up to 500mA and higher reverse blocking voltage up to 70V. According to the company, the micro-packaged Schottky diodes are ideal for use in camera flash and module drivers, boost converters for LCD/ or keypad backlighting and a wide range of DC/DC converter applications in space-constraint portable applications. The Schottky diodes are highly optimized for lower forward voltage drop and lower leakage current resulting in higher efficiency and lower losses, says ON Semi. The SOD-923 packaged Schottky diodes are available in the lead-free, halogen-free packages and budgetary priced at $0.064 per unit in 8,000 quantities.

Zener diodes
The Zener portfolio from ON Semiconductor now features the NZ9F series in the tiny SOD-923 package measuring only 1mm x 0.6mm x 0.4mm. With a steady state power dissipation of 200mW, the NZ9F series offers the same power handling capability as the SOD-323 package in a fraction of the board space. This series features a full Zener breakdown voltage range from 2.4V to 24V with both 2 percent and 5 percent tolerance devices. Typical applications for these Zener diodes include voltage reference, low current voltage regulation and voltage clamping. Budgetary pricing for these devices is $ 0.04 per unit in 8,000 unit quantities.
