TVS - Diodes are an important component in the electronics industry as these devices help protect sensitive circuits from power surges. The most commonly seen device of this type is the DF2B7ACT,L3F, an unidirectional transient voltage suppressor that has a working voltage of 72V and peak pulse power of 275W. It is used in applications where overvoltage protection is needed and also offers thermal protection.

Application Field

The DF2B7ACT,L3F is intended as overvoltage surge protection for digital, analog or mixed signal circuits. It can be used as a device to help safeguard circuits from overcurrents, ESD and transients caused by switching operations or other voltage fluctuations in the system. Particularly, it is routinely used in automotive, industrial, telecommunications and consumer electronics applications.

Working Principle

The DF2B7ACT,L3F device is a two-terminal unidirectional transient suppressor that operates during voltage transients. The device contains a thyristor which switches on within nanoseconds of the voltage surge and limits the maximum voltage level to the device rated voltage. The device then dissipates the power in the form of heat or lights depending on the device.

This device is also equipped with a suppression diode which offers protection independent of the thyristor. During voltage transients up to the rated voltage for the DF2B7ACT,L3F, the suppression diode remains open and thereby does not conduct any current. When the voltage exceeds the rated value, it then turns on and conducts current from the anode to the cathode and thereby reduces the voltage.

The DF2B7ACT,L3F has a working voltage of 72V and peak pulse power of 275W. It is designed to help protect sensitive circuits from overvoltage transients, ESD and surge current. The suppression diode offers additional protection by reducing the voltage beyond the specified working voltage. And finally, the device also offers thermal protection when the temperature exceeds a certain value.

Conclusion

The DF2B7ACT,L3F is an important device in the electronics industry as it helps protect sensitive circuits from overvoltage transients, ESD, and surge current. The working principle of this device is based on a thyristor that switches on within nanoseconds of the voltage surge and limits the maximum voltage to the device rating. In addition, it contains a suppression diode which offers additional protection by reducing the voltage when the device is overloaded. It is useful in various applications such as automotive, industrial, telecommunications and consumer electronics applications. With its reliable power protection function, it is a valuable component for a variety of electrical circuits.
