ESD electrostatic protection
|
Information of ESD 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). |
