Thyristors are an important family of semiconductor components whose main purpose is to help regulate and control the flow of electricity. The TB0720M-13 is a thyristor that provides lightning protection to high voltage applications. It can operate up to 20 amps, allowing for the single-phase protection of lighting systems operating up to 720 Volts. In addition, this thyristor is designed for low-loss operation and is capable of providing short-circuit and arc-fault protection.

The TB0720M-13 is a high efficiency, UL recognized, thyristor-based device. It features an innovative Zener diode that provides fast response to transient voltage spikes. The device is designed to provide both phase and neutral ground protection in a single package. The device is also reverse biased when off, and provides bidirectional protection across all three lines.

The TB0720M-13 works by sensing electrical current flows in the lines. When the current flow is greater than the predetermined level, the thyristor is triggered and an arc is created. This arc can then be connected to an electrical system to provide protection against over-voltage or over-current. Additionally, the device’s unique circuitry allows for the protection of very low voltages over short distances as low as 0.1 volts in 20 cm.

To further increase the device’s effectiveness, the TB0720M-13 is designed to be used in conjunction with other protection devices. When combined, these devices can provide a comprehensive lightning protection solution. For example, the device can be used with a single-pole surge arrester to provide a continuous, shielded arc protection. Additionally, the device can be used with an auxiliary ground loop device to provide fast response to circuits that are subject to multiple transient disturbances.

In summary, the TB0720M-13 thyristor provides fast response and high efficiency in lightning protection applications, along with the ability to be used with additional protection devices. Its Zener diode gives it the ability to detect and react to transient voltage spikes, and its reverse bias allows for bidirectional lightning protection, making it a great choice for single-phase lighting systems.
