[0041] The static electricity elimination circuit can include an ESD static electricity protection diode, which is a device for protecting electronic circuits, devices and equipment from static damage, which can provide fast voltage protection when an electrostatic discharge (ESD) event occurs. Common ESD static electricity protection diodes are, for example: ESD9B3.3ST5G brand: onsemi (onsemi) package: SOD-923, polarity: bidirectional, reverse breakdown voltage (Vrwm): 3.3V, maximum clamping voltage: 11.5V, peak pulse current (Ipp) @10 / 1000us: 2A.

When the applied voltage increases to exceed the insulation strength of the gas, the gap between the two poles will be discharged and broken down, changing from high impedance to low impedance. When discharging, an electric arc is generated, and the arc voltage is about 30V. After conduction, the voltage between the two poles of the discharge tube is maintained at the arc voltage value level. Commonly used glass discharge tubes, for example: BK33000702-M brand: Brightking (Jun Yao Electronics), package: SMD, 1.4x3.4mm, description: high-efficiency discharge tube, DC breakdown voltage: 140V, precision: ±30%, insulation resistance: 100MΩ, static capacity: 0.8pF
