TVS - Mixed Technology

The 4B06B-540-290/290 is a type of mixed technology thyristor surge protection device (TVS - Mixed Technology). It is designed to protect sensitive electronic systems from high energy transients caused by lightning and other similar events. It also protects against over-voltage and over-current events due to excessive input voltage or load. The device is suitable for use in both AC and DC applications.

Application

The 4B06B-540-290/290 is a popular choice for applications in industrial, automotive, medical, telecom and other sensitive equipment. It is typically used for the protection of input and output lines in AC and DC power supplies. It is also used to protect light sources, sensors and other sensitive electronic devices. This device can also be used to protect cables and other devices from over-voltage and over-current conditions.

Working Principle

The 4B06B-540-290/290 works on the principle of breaking down a high voltage current flow and thus providing a protection layer. This device is composed of two main parts: a thyristor and a resistive element. The thyristor is the active element and it is responsible for conducting voltage across its terminals in a single direction when a voltage greater than the nominal voltage is applied to it. Once the thyristor turns on, the resistive element starts to act as a load to limit the current flow, ensuring that the current does not exceed the specified peak value and damaging the equipment.

Advantages

The 4B06B-540-290/290 offers several advantages compared to conventional surge protection devices. It provides superior over-voltage protection with very low power dissipation while not introducing any significant inductance or frequency limitations. This device also offers excellent response time and diagnostic features. It is able to detect over-voltage events and respond immediately and effectively. Additionally, the device generates minimal EMI and RFI interference.

Conclusion

The 4B06B-540-290/290 is a type of TVS - Mixed Technology device which offers excellent protection against lightning and other high-energy transients. It provides superior over-voltage protection and is suitable for AC and DC applications. Additionally, this device has very low power dissipation and generates minimal EMI and RFI interference. It also offers excellent response time and diagnostic features. This device is a popular choice for applications in industrial, automotive, medical, telecom and other sensitive equipment.
