Characteristics of ESD electrostatic protection devices

ESD electrostatic protector is an overvoltage, anti-static protection element used to protect sensitive circuits in electronic equipment from the effects of ESD (electrostatic discharge). Its role is to transfer ESD stress from the sensitive element and allow current to flow through the protective element instead of sensitive element, while maintaining low voltage on the sensitive element;ESD electrostatic protector should also have low leakage and low capacitance characteristics and will not reduce circuit function; It will not cause damage to high-speed signals, and the function of the protection element will not be degraded under multiple stresses.

Product characteristics of ESD electrostatic protector:

1. Fast response (action) speed (less than 1ns)

2. Low capacitance value (suitable for high-frequency high-speed transmission lines)

3. Small size and diversified packaging (can meet the application needs of various products)

4. Low leakage current (less than 1uA)

5. Ultra-low limiting voltage (clamping voltage)

6. Low voltage value (reverse cutoff voltage is commonly known as the maximum non-operating voltage)
