ESD ( Electrostatic Discharge Protection Devices ), also called TVS (Transient Voltage Suppressors ) Array，is a single-channel or multi-channel ESD protection device with specific functions designed by multiple TVS grains or diodes with different layouts . ESD is the most ideal high-frequency data protection device because of these unique features : quick response speed (less than 0.5ns), low capacitance, low on-off voltage, high integration, small size, easy installation, protecting multiple data line protection at the same time.

At present, ESD that it is supplied by DOWO is mainly used for electrostatic protection of various communication interfaces , for example USB , HDMI , RS485 , RS232, VGA, RJ11, RJ45, BNC, SIM, SD, etc. And, DOWO supplies various encapsulations, from single SOD-323 to multiple SOT-23, SOT 23-6L, QFN-10, etc. Circuit design engineers can select ESD with different encapsulations according to circuit board layout and interface types.
