ESD protection arrays

12 November 2008 Circuit & System Protection

ON Semiconductor has released two new members of its low capacitance electrostatic discharge (ESD) protection product line – the NUP4016 and the ESD11L5.0D. These new products utilise a patented, integrated ESD protection platform, which enhances clamping performance while maintaining ultra-low capacitance and small die size.

Offered in ultra-small packages that provide a 20% lower profile than previous package versions, they are ideal protection devices for portable applications such as mobile phones, MP3 players, flat panel displays and other high-speed communication applications requiring high protection in an ultra-slim package.

The NUP4016 protects four high-speed data lines in the tiny 1,0 x 1,0 x 0,4 mm SOT-953 package. It also has ultra-low capacitance of 0,5 pF per I/O line which make it suitable for protecting high-speed interfaces such as USB 2.0 high-speed (480 Mbps) and HDMI (1,65 Gbps).

The ESD11L5.0D protects two high-speed data lines at 0,5 pF in the ultra-small 1,0 x 0,6 x 0,37 mm SOT-1123. Integrating ultra-low capacitance technology into a 3-pin package provides designers with a solution to protect the D+ and D- lines of a USB2.0 port with a single device. The device can also be connected cathode to cathode to protect a single bi-directional line at 0,25 pF, ideal for protecting high-frequency RF antenna lines.

Both devices are capable of clamping an input ESD waveform of 15 kV to less than 8 V in a matter of nanoseconds and are free from wearout mechanisms that affect the reliability and performance of passive technologies after multiple surge events such as ESD.
