ESD electrostatic protector is also called ESD, ESD protection diode, ESD diode, ESD electrostatic diode, anti-static diode, TVS Array, etc. ESD English name: Electrostatic Discharge means "electrostatic discharge", abbreviated as ESD; Adopt semiconductor material, crystal grain, metal and resin for encapsulation and molding. Moreover, ESD electrostatic protection devices have been formed since the middle of this century to study the generation and attenuation of static electricity, electrostatic discharge models, electrostatic discharge effects such as electro-thermal (spark) effects (such as ignition and explosion caused by static electricity) and electromagnetic effects (such as electromagnetic interference).
The ESD electrostatic protection device represented by Shenzhen Shunhai Technology is mainly composed of TVS ARRAY, which is designed into single-channel or multi-channel ESD electrostatic protection devices with characteristic functions and devices packaged in different ways through multiple TVS grains or diodes. Its advantages are small size, low junction capacitance and fast response speed. Its brands can be elected from domestic famous brands such as "Shuokai" and "Saruiwei". Commonly used packages are DFN0603-2, DFN1006-2/3, DFN2020, SOD-923, SOD-523, DFN1616, SOD-323, SOD-123, DFN2626, SOT-523, SOT-23 and dfn306. DNF2020, SOT-536, DFN2510, DFN2116, etc. If you need ESD electrostatic protection devices, please leave a message or call 0755-28100016; Massive TVS/ESD electrostatic protection devices are in stock, welcome to take samples for testing. Then the following small series generally introduces the parameters and specifications of ESD electrostatic protection devices of one brand and package series as follows.

Parameter identification diagram of ESD electrostatic protector is as follows
Characteristics of ESD electrostatic protector
Diversified packaging forms;
Low capacitance, the lowest can reach a few tenths of picofarads;
Fast response time: usually less than 1.0PS；;
Small size, miniaturized devices, saving PCB space;
The working voltage can be designed according to the working voltage of IC, such as 2.8V, 3.3V, 5V, 12V, 15V, etc.
High flexibility, which can design parameters such as capacitance, packaging form and surge capacity according to application requirements;
Matters needing attention in selection of ESD electrostatic protector
(1)ESD is generally used for electrostatic protection of various communication ports. In some high-speed data lines, such as USB3.0, HDMI, IEEE1394 and other interfaces, the junction capacitance of ESD electrostatic protection diode should be elected as small as possible to avoid affecting the communication quality;
(2)ESD can be divided into one-way (A) and two-way (C), which can be elected according to working signals. One-way ESD or two-way ESD can be elected for unipolar signals, and two-way ESD should be elected for bipolar signals;
(3) If you don't know what type of ESD electrostatic diode to choose for electrostatic protection, you can contact our professional engineer to help you choose the type according to the product;
The application of ESD electrostatic protector
ESD electrostatic protector is widely used in HDMI interface, portable video equipment, LCD plasma TV, USB2.0 and IEEE1394 interface, GPS system, portable equipment (PDA, DSC, bluetooth), printer interface, satellite receiver, DVI, antenna, etc. to improve the protection of sensitive electronic components.
