NUP4016, ESD11L5.0D

ON Semiconductor introduces two new members of its low capacitance ESD protection product line, the NUP4016 and the ESD11L5.0D. According to the company, the use of patented, integrated ESD protection platform enable the new devices to enhance clamping performance while maintaining ultralow capacitance and small die size. Offered in ultrasmall packages that provide a 20 percent lower profile than previous package versions, the NUP4016 and the ESD11L5.0D are designed as protection devices for portable applications such as mobile phones, MP3 players, flat panel displays and other high-speed communication applications requiring superior protection in an ultra-slim package.

The NUP4016 protects four high-speed data lines in the tiny 1mm x 1mm x 0.4mm SOT-953 package, making it the lowest profile ESD device for high speed communication interfaces on the market today, touts ON Semiconductor. It also has ultralow capacitance of 0.5 pico farad (pF) per I/O line which makes it suitable for protecting high speed interfaces such as USB 2.0 high speed (480Mbit/s) and HDMI (1.65Gbit/s).

The ESD11L5.0D protects two high speed data lines at 0.5pF in the ultrasmall 1mm x 0.6mm x 0.37mm SOT-1123 making it the lowest profile ESD device for high speed communication and USB 2.0 data and power line and protection available on the market today, says ON Semiconductor. The SOT-1123 package offers a 50 percent smaller footprint and 20 percent lower height than comparable solutions offered in a SOT-723 .Integrating ON Semiconductor's ultralow capacitance technology into a 3-pin package provides the designer with a solution to protect the D+ and D- lines of a USB2.0 port with a single device. The ESD11L5.0D can also be connected cathode to cathode to protect a single bi-directional line at 0.25pF, ideal for protecting high frequency RF antenna lines.

Both the NUP4016 and ESD11L5.0D are capable of clamping an input ESD waveform of 15kV to less than 8V in a matter of nanoseconds.

The NUP4016 is available in a SOT-953 package and is priced at $0.40 per unit in 3,000-unit quantities. The ESD11L5.0D is available in a SOT-1123 package and is priced at $0.21 per unit in 8,000-unit quantities.
