ESD protection diode has fast response speed (less than 0.5ns), low capacitance, low on-voltage, high integration, small size, easy installation, can realize multiple data line protection at the same time, is the most ideal high frequency data protection devices in the industry.

ESD ESD protection diode is mainly used for ESD protection of various communication interfaces, such as USB, HDMI, RS485, RS232, VGA, RJ11, RJ45, BNC, SIM, SD, etc. At the same time, ESD electrostatic protection component package is diversified, from single channel SOD-323 to multi-channel SOT-23, SOT23-6L, QFN-10, etc. Circuit design engineers can choose different packages of ESD electrostatic protection diodes according to the layout of the circuit board and interface type.

TVS transient suppression diode and ESD electrostatic diode work in the same principle, but in terms of power, application, packaging form, etc., the specific performance is as follows:

1) ESD electrostatic diode, the main function is anti-static, but anti-static requires low capacitance value, generally between 1- 3.5PF best; The capacitance value of TVS diode is relatively high.

2) ESD protection diode, mainly used in board level protection; TVS diodes are used for primary and secondary protection.

3) When selecting ESD diode, more attention is paid to ESD diode's ESD rating (HBM/MM) and IEC61000-4-2 LEVEL. High-speed USB and I/O attach great importance to ESD diode's C; When TVS diode is selected, the power and package form are looked at;

In practical application, the two usually complement each other, closely linked, each play their advantages, more effectively protect the circuit safety.
