Protecting electronics from damaging discharges

Paul Boughton

Littelfuse has introduced the XGD Series XTREME-GUARD ESD Suppressor, available in 0402- and 0603-sized, flat-topped surface mount packages.

It protects sensitive electronics against electrostatic discharges as high as 30kV and is suitable for high voltage applications up to 32VDC.

When correctly integrated into a circuit design, the XGD Series can safely absorb repetitive ESD strikes nearly four times the maximum level specified in the IEC61000-4-2 international standard without performance degradation.

Extremely low capacitance makes the XGD Series suitable for use in high-frequency and high-speed data, video, antenna and I/O circuits. Even after multiple ESD strikes, it exhibits ultra-low current leakage (<1nA), ensuring minimal power losses, so it’s well-suited for protecting battery-powered electronics like wearables.

Both sizes offer much higher voltage ratings than other ESD suppressors with similar board footprints; they also offer far greater ESD protection than many TVS Diodes while providing much lower capacitance and leakage current and higher voltage ratings.

Applications can be found in the industrial, consumer electronics, telecom/datacom, and white goods/home appliances markets.
