CGA0805MLA-38201E

TVS or transient voltage suppression devices, such as the CGA0805MLA-38201E, are an important tool in the arsenal of electronic engineers. TVS devices are designed to protect sensitive electronic circuits from lightning strikes, electrostatic discharge (ESD), and high-energy impulses that can occur in modern electronics. In this article, we will take a look at the application field and working principle of the CGA0805MLA-38201E TVS.

Application Field

The CGA0805MLA-38201E is an avalanche TVS (Transient Voltage Suppressor) that is designed to protect sensitive circuits from transients that can occur in modern electronic systems. It is commonly used in automotive applications, where high voltage transients are common due to the various systems that are in use. It is also widely used in other mobile applications such as handheld devices and wireless communication systems. The CGA0805MLA-38201E is also suitable for use in industrial systems, where there is a possibility of high-energy transients caused by switching and induction.

Working Principle

The CGA0805MLA-38201E operates by using an avalanche breakdown mechanism to suppress transient overvoltages. Avalanche breakdown occurs when a reverse voltage is applied to a semiconductor junction, creating a high current flow. This high current flow is capable of quickly suppressing transients. The CGA0805MLA-38201E is designed with a breakdown voltage of 28V and a 10V peak pulse power rating, making it suitable for a wide variety of applications.

In order to ensure that the avalanche breakdown occurs quickly, the CGA0805MLA-38201E is designed with an internal avalanche diode and a high-speed diode connected in series. The avalanche diode helps to ensure that the breakdown voltage is effectively converted to an avalanche current, and the high-speed diode limits the current flow to prevent any damage to the device. The CGA0805MLA-38201E is also designed with an external bypass capacitor, which helps to improve its transient suppression performance.

Conclusion

The CGA0805MLA-38201E is a high-performance avalanche TVS device that is designed to protect sensitive electronic circuits from transients such as lightning strikes and electrostatic discharge. It is suitable for use in auto, mobile, and industrial electronics, and is designed with an internal diode and bypass capacitor to ensure fast, reliable protection.
