ESD protection arrays deliver lower profile, low capacitance

Phoenix, Ariz. — ON Semiconductor has added two new devices to its low capacitance electrostatic discharge (ESD) protection product line. The NUP4016 and ESD11L5.0D products use ON Semiconductor's integrated ESD protection platform, which enhances clamping performance while maintaining ultra-low capacitance and small die size.

Offered in ultra-small packages that provide 20 percent lower profile than previous package versions, the NUP4016 and ESD11L5.0D, touted as the lowest profile ESD protection devices in the market, are suitable for portable applications such as mobile phones, MP3 players, flat panel displays and other high-speed communication applications.

The NUP4016 protects four high-speed data lines in a 1.0 x 1.0 x 0.4-mm SOT-953 package. This device also provides an ultra-low capacitance of 0.5 picofarad (pF) per I/O line, which makes it suitable for protecting high-speed interfaces such as USB 2.0 high-speed (480 Mbits/s) and HDMI (1.65 Gbits/s).

The ESD11L5.0D protects two high-speed data lines at 0.5 pF in a 1.0 x 0.6 x 0.37-mm SOT-1123 package. 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 ultra-low capacitance technology into a 3-pin package provides the designer with a solution to protect the D+ and D- lines of a USB 2.0 port with a single device. The ESD11L5.0D can also be connected cathode-to-cathode to protect a single bi-directional line at 0.25 pF, suitable for protecting high frequency RF antenna lines.

Both the NUP4016 and ESD11L5.0D are capable of clamping an input ESD waveform of 15 kilovolt (kV) to less than 8 volts (V) in a matter of nanoseconds, ensuring the highest levels of protection for today's ESD sensitive integrated circuits (IC), said ON Semiconductor. In addition, these silicon devices are free from wearout mechanisms that affect the reliability and performance of alternative passive technologies after multiple surge events such as ESD, according to the company.

Pricing: The NUP4016 (SOT-953 package) is priced at $0.40 each in quantities of 3,000. The ESD11L5.0D (SOT-1123 package) is priced at $0.21 each in quantities of 8,000.
