ESD static protection components

Information of ESD
Electrostatic Discharged Protection Devices, referred to as ESD. It is mainly used to protect the Electrostatic Discharge of communication interface .

The reason of Electrostatic Discharge：

a. Two substances via the contact friction and loss of electrons or the electron, the charge band (no flow) termed static;

b. Due to switch electricity or lightning induced surge also indirect causes static electricity;

c. Temperature and humidity affect the turboelectric charged, at less than 45℃, it will produce higher humidity greater voltage more than in 55℃, damaging also relatively large.

The selection tips of ESD

1. The Vrwm is bigger or equal to the circuit working voltage is better;

2. The Cp of ESD is confirmed by the rate of data port, the data transfer more faster ,the Cp of ESD should be more smaller;

3. Selecting suitable Ipp for your circuit, the suitable Vc for your circuit and power=Ipp*Vc*power factor;

4. According to the PCB to select package (1-channel or multi-channels).
