Device.
Background technique
Electrostatic be one kind be present in body surface, reflect its positive and negative charge in subrange the phenomenon that disequilibrium, it
The main contact by substance with separate, the physical processes such as electrostatic induction, dielectric polorization and charged particle attachment generate, show
Higher for voltage, the duration is very short, releases energy the features such as not strong.With the development of rapid photo detector, electrostatic is to member
Device is more and more obvious using caused harm.The purpose for introducing electrostatic protection element seeks to that operating circuit is avoided to become quiet
The access of discharge of electricity and damaged, which not only wants that electrostatic induced current can be absorbed, and clamps the voltage of operating circuit, prevents it
Be damaged due to voltage overload, also want can electrostatic occur when quick response, while protecting circuit, self structure can not
It is damaged.An important factor for electrostatic protection need to consider when having become overvoltage protection design.
The awareness of safety constantly promoted pushes and expands the development of over-current over-voltage protection product, in product design, no
Only to guarantee the performance requirement of circuitry, even more to focus on their security feature.Electronic system often by it is extraneous because
Element interference, such as on-off inductive load or start and stop high power load, line fault, thunder and lightning etc. cause instantaneous overvoltage or overcurrent
Phenomenon, they have serious harm for the trouble free service of electronic system, gently then lead to equipment fault, signal interruption；It is heavy then cause
Equipment and cable are burnt, and are jeopardized the safety of operator, are led to major accident.So generally requiring design anti-surge protective device
To carry out the protection of two over-voltage, overcurrent aspects to electronic equipment and transmission line of electricity.Traditional overcurrent protection is needed in circuit
Middle serial fuse structure causes metal bath exothermic melting and disconnecting circuit using overload current；Equally, traditional over-voltage is protected
Shield is realized with shunting mode parallel connection over-voltage protection element, is generally shorted surge voltage and the earth, is diverted into surge current
Ground achievees the purpose that weakening and eliminates overvoltage, overcurrent, to play the role of protecting electronic equipments safety operation.But this
A little discrete overcurrents and over-voltage protector are other than defencive function is single, there is also there is many defects, if response speed is slower,
Reliability and stability difference etc.；On the other hand, with the continuous enhancing of electronic functionalities, the density of internal component also exists
Constantly rise, thus it requires the component with identical operating current, voltage and resistant to flow grade can further decrease its size.
Therefore, it is necessary to propose a kind of static suppressor with electrostatic protection function in response to the above problems.
