NUP45V6 ESD protection arrays from ON Semi

ON Semiconductor has introduced a series of low-capacitance ESD protection arrays in an ultrasmall SOT-953 package. Measuring 1-by-1mm with a 0.5mm profile, these devices are suitable for applications where board space is at a premium. Designed for a wide range of sensitive equipment, these devices are optimized for use in cellphones, PDAs, digital cameras and other protection applications.

These SOT-953 packaged devices are 60 percent smaller than the SOT-553 ESD protection diode arrays also available from ON Semiconductor. The SOT-953 provides 30 percent space savings compared to the 1-by-1.45mm Micro-QFNcurrently the next smallest package available in the market.

The NUP45V6 series offer four independent lines of protection from ESD and other harmful transient voltage events. This new series includes devices with protection voltages of 5.6-, 6.8- and 12V and provide IEC61000 Level 4-2 ESD performance. Because of their miniature size, these diodes can be placed near I/O ports to suppress the transient voltage before it can be coupled into the rest of the board.

Delivering low capacitance of less than 7pF at 3V, and low leakage current of less than 0.1?A, the company said these integrated devices are highly efficient and offer reliable protection.

"By offering innovative board-level solutions like the ultrasmall packaged NUP45V6 series, ON Semiconductor directly addresses the needs of design engineers," said Hyung-Sup Kim, ON Semiconductor's marketing director for the consumer products division.

The NUP45V6, NUP46V8 and NUP412V are priced at 12 cents in quantities of 10,000.
