Advantages of electrostatic diodes

What are the advantages of electrostatic diodes? When using electrostatic diodes, it is not only necessary to understand their principles, but also to consider their advantages when selecting diodes.
Electrostatic diodes have a relatively small volume, low junction capacitance, and fast response speed. When ESD diodes are connected in parallel in a circuit, they are in a (high resistance state) cutoff state during normal operation, which does not affect the normal operation of the circuit. Therefore, when an abnormal overvoltage occurs in the circuit and reaches the breakdown voltage, it will change from a high resistance state to a low configuration, providing a low impedance conduction path for instantaneous current and clamping the abnormal high voltage within a safe level, thereby protecting the protected IC or circuit; When the abnormal overvoltage disappears, it returns to the high impedance state and the circuit works normally.
