Broad portfolio of standard components offered in new SOT-723 package deliver low profile and more than 80 percent reduction in footprint without sacrificing power dissipation performance

PHOENIX, Ariz. – April 5, 2005 – Responding to the portable product industry’s need for further miniaturization of discrete component packaging, ON Semiconductor (NASDAQ: ONNN) has introduced more than 50 small signal transistors and small signal diodes in a SOT-723 flat-lead package. This new package utilizes only 1.44 mm2 of printed circuit board (PCB) area, improves the silicon-to-package ratio and delivers superior power dissipation performance.

"ON Semiconductor is leading the move to offer small signal devices in the SOT-723 package with one of the widest selections of technologies available," said Mamoon Rashid, ON Semiconductor general manager for the Small Signal Division. "For our customers, especially those in the portable products segment, these devices help them to offer the best combination of increased functionality, dfunctionality, decreased size and greater power efficiency."

The discrete devices to be offered in the SOT-723 package include digital transistors, bipolar transistors, small signal Schottkys and small signal switching diodes. With package dimension of 1.2 mm x 1.2 mm x 0.5 mm, the SOT-723 package helps free-up much needed board space in cell phones, PDAs, digital still cameras, notebook computers and other applications.

Compared to the industry’s commonly used SOT-23 package, the SOT-723 delivers a footprint reduction of 84 percent and a profile improvement of 50 percent. Compared to standard gull-wing packages, the flat-lead design of ON Semiconductor’s SOT-723 devices results in up to a 20 percent improvement in power dissipation and up to 12 percent improvement in thermal resistance (Theta J-A). This delivers superior heat dissipation performance per unit of board area.

The devices are priced between $0.016 and $0.04 per unit in quantities of 10,000 units.
