TVB058NSB Thyristors are power electronic components used for reducing transient overvoltage in the application of AC and DC power. It works as a solid state switch in the electronic circuits, and can also be used for control of power devices, and as controls for electrical equipment.The TVB058NSB is a medium-to-full range thyristor that offers a high voltage capability and contains a built-in surge limitation circuit. This device is designed for the protection of power supply lines, industrial equipment, and other applications where transient overvoltage must be reduced or eliminated. The TVB058NSB is commonly used in power line protection, motor protection, voltage regulation and protection of switching power supplies. It is also used for energy recovery applications in high speed switching power amplifiers.The TVB058NSB has a thyristor structure in a four layer silicone chip technology, which provides a low power loss capability. The thyristor has an active gate and a static gate for controlling firing, overvoltage protection and current limit protection. The static gate has an integral zener diode, which connects to the external circuit and helps to regulate the gate voltage. The active gate control is used to turn the thyristor off in the event of an overvoltage. This active gate control is also used to control the gate current that is necessary for firing the device.Once the device is fired, it will remain in the ON state until the forward current falls below the holding current. This is determined by the gate voltage and is typically around 1mA. When the current falls below the holding current, the device will immediately turn OFF. This makes the TVB058NSB an ideal device for applications where fast turn-off is required.The TVB058NSB provides excellent protection against transient and surge voltage, and overvoltage protection up to 200V. It also offers low power loss and short circuit protection, which prevents damage to the device and other components. Furthermore, the device has a fast switching time, which ensures that the overvoltage or transient voltage will not cause any damage to the power supplies or other electronic components in the system.Overall, the TVB058NSB is a reliable and cost-effective thyristor for use in applications where power protection and overvoltage protection are required. Thanks to its fast switching time and overvoltage protection up to 200V, the device is a suitable choice for many applications. It also offers low power loss and short circuit protection, which makes it a dependable choice for protecting power supplies and other electronic components.
