ESD is to produce and attenuation model electrostatic discharge, electrostatic discharge effect as the current heat (spark) effect since mid-century in order to study the formation of static electricity (such as fire and explosion caused by static electricity) and electromagnetic effects (electromagnetic interference) and other disciplines . In recent years, with the rapid development of science and technology, widely used in microelectronics technology and electromagnetic environments become more complex, the effect of electrostatic discharge electromagnetic fields such as electromagnetic interference (EMI) and electromagnetic compatibility (EMC) issues more seriously.
ESD electrostatic suppressor has been to prevent static, anti-surge, anti-jamming for the character. Commonly used in communication lines and interfaces, protect sensitive electronic circuitry from electrostatic damage. ESD protection devices commonly used models generally: 323 package RLSD32A031C, RLSD32A051C, RLSD32A031V, RLSD32A051V, SOT-23 of RLST32A032V, RLST32A052V; the high-frequency circuit commonly used models generally have low capacitance: RLSD92Q051LC, RLSD32A031LC, RLSD32A051LC, RLSD32A081LC, RLSD32A121LC, RLSD32A151LC, RLSD32A241LC like. Various types of digital products, functionality is now more powerful, while the board is getting smaller, more integrated. And are more or less partially filled with an interface for human-computer interaction.
