TVS - Diodes

A transil, commonly referred to as a TVS (transient voltage suppressor), is an overvoltage protection device used to protect against electrostatic discharge (ESD), fast transient overvoltages, and electro-magnetic interference (EMI). A TVS diode, also known as Transil, is a form of protection device that is specifically designed to help protect against high voltage transients. TVS Diodes, or Transil, are small devices employed to protect all kinds of components from damage or destruction due to transient overvoltage.

SA20CA-E3/54 Application Field and Working Principle

The SA20CA-E3/54 is a series of low-power, fast response, unidirectional,TEOPLEX TVS diode arrays with an IEC 61000-4-2 contact ESD rating of 6kV, and a IEC 61000-4-2 air discharge ESD rating of 10kV. It is designed for a reverse stand-off voltage of 7.8VDC and can work with a forward current of 0.2A, peak pulse current of 8A. It is mainly used in the automotive industry, telecommunications industry, computers and other applications.

TVS diodes work by clamping the overvoltage transients to a safe level near ground. When a transient overvoltage strikes, the TVS diode acts quickly by grounding the voltage across the diode and releasing the stored charge. The clamping effect effectively reduces energy transmission within the device and hence to the downstream circuitry. This keeps the device at a safe voltage level and reduces the risk of damages. In effect, SA20CA-E3/54 provides unparalleled protection against hazardous overvoltage transients.

TVS diodes also protect against surges caused by power surges and inductive transients. They can be used for both single- and multiple-phase surge suppression. The SA20CA-E3/54 has a high surge withstanding capability and fast response time, making them suitable for use in a variety of application areas. These include automotive, telecommunications, computers, medical equipment, and various industrial control systems.

Apart from overvoltage protection, the SA20CA-E3/54 also provides ESD protection for both electronic and electrical systems. ESD protection helps to protect against high voltage transients due to electrostatic discharges that arise from human body or tools. The device provides bidirectional protection, making it suitable for a wide variety of circuits. This helps to protect delicate electronic components and devices from ESD damage.

Overall, the SA20CA-E3/54 is a versatile TVS diode that provides excellent protection against overvoltage, electrostatic discharge (ESD), and power surges. It is suitable for a variety of applications such as automotive, telecommunication, computer, medical equipment, and industrial control systems. It is a low-power, fast response, unidirectional device that has a IEC 61000-4-2 contact ESD rating of 6kV, and a IEC 61000-4-2 air discharge ESD rating of 10kV. Its fast response time and high surge withstanding capability make it an ideal choice for a wide variety of applications.
