ESD Suppressor

ESD suppressors are semiconductors that protect electronic components and systems from electrostatic discharge (ESD), the sudden and uncontrolled transfer of an electrical charge between conductors. They are installed near the protected line and connected in parallel with the signal line.

We are fully committed to producing technologically advanced ESD Suppressor.

Most products consist of diode arrays. ESD suppressors protect static-dissipative equipment from overvoltage transients by clamping voltages to levels which circuits can withstand. They shunt the majority of the ESD current away from the data line to a reference, usually the power rail and chassis ground.

ESD Suppressor Manufacture Process:

ESD Suppressor Advantages:

From the term of Electrostatic discharge commonly known as ESD, we mean a sudden flow of electricity between two electrically charged objects. It can be produced via contact, by an electrical short, or because of dielectric breakdown. The main reason of the ESD appearance is due to the closeness of differently-charged objects or come within them in the situation when the dielectric between these objects breaks down that may create a visible spark as well.

ESD Suppressor Application:

During production, transient voltage suppression (TVS) increases chip yields according to standards such as charged device model (CDM) and machine model (MM). During end-use, ESD suppressors protect electronic products such as cell phones, personal digital assistants (PDA), and computers according to test methodologies such as IEC 61000-4-2 from the International Electrotechnical Commission (IEC).

1. What is ESD suppressor?

ESD suppressors are semiconductors that protect electronic components and systems from electrostatic discharge (ESD), the sudden and uncontrolled transfer of an electrical charge between conductors. They are installed near the protected line and connected in parallel with the signal line.

2. How does ESD suppressor work?

When the interface signal is passing through the system, the ESD diode is effectively invisible and no current passes through it. However, when an ESD strike occurs the voltage across the diode exceeds a certain threshold known as the breakdown voltage. And the diode begins to conduct and shunt current to ground.

3. What is a ESD suppressor used for?

ESD diodes are ideal for protecting high speed data line applications, Polymer ESD Suppressor devices offer extremely low capacitance and small size — they ensure ESD protection while ensuring signal integrity. ESD Suppressors can be applied in many areas, such as PC's, Portable Medical Devices, LCD, Portable Navigation Devices, Keyboard, Mobile Handsets, MP3/PMP's, Digital Cameras, SIM/SD Cards, External Storage, Switched/RRouters, Smart Phones, etc.

4. How to select the best ESD suppressor for your electronic application?

To select the ideal ESD protection solution for a given application, we must understand both the system that needs protection, as well as the properties of protection devices. The ESD device must not disturb the functionality of the system it is protecting, and also must react quickly to shunt dangerous current and voltage spikes to ground during surge and ESD events...Read more

5. Where should ESD diodes be placed?

ESD protection diode must be placed as close to the pin that it is protecting as possible and its connection to the reference plane must be made as close to the anode pin as possible.
