Stackpole Electronics Inc’s discrete (ESD Series) and array
(ESA Series) suppression devices are ideal for ESD protection of high speed
communications ports, such as USB 2.0.
These products offer capacitance as low as 0.01 pF, which
preserves signal integrity even up to data rates approaching 5 GHz. Like other
gap type devices, the ESD and ESA have very low leakage current. However, the
unique air gap technology from Stackpole offers protection for thousands of ESD
events versus the polymer gap devices that can degrade after only a few ESD
events. For single USB ports, a single ESD0603 or ESD0402 is ideal for its
small size and weight and low cost. For multiple USB ports, the ESA Series 0603
by four-array has four ESD type devices on a single chip array package for even
more volumetric efficiency.
The ESD Series and ESA Series are available in operating
voltages of 3.3, 5.5, 12, and 24 volts, and in clamping voltages of 17 and 25
volts.
