Thyristors - SCRs - Modules is a broad category of power electronic components that refer to solid state switches that can reverse the direction of current when a signal voltage, current, or temperature exceeds a certain threshold. The VS-T70RIA60 module is one such device falling under this category, with a field of application and working principle that both deserve to be discussed further.

Application Field

The VS-T70RIA60 is a multipurpose device, designed to be used in a range of high power applications. It features a rugged design for reliability in industrial, marine and other harsh environments. As a result, the device is especially suitable for application fields such as high-power motor control, voltage regulation, ups systems, energy storage systems, and more.

The device’s high current capacity and low on-state voltage drop also make it suitable for application in current limiting circuits, voltage regulation and other control systems. Its reverse blocking capabilities provide protection and isolation when disconnecting circuits and components, meaning it can also be used in power plant protection systems and high voltage switchgear.

Working Principle

The VS-T70RIA60 is a two-terminal two-stage semiconductor switching device that operates under pulse-controlled logic. It works by both controlling the ON and OFF voltage, as well as the OFF-period current of the connected load. When the control circuit sends a low-voltage pulse to the device, it switches on and allows the current to flow through the device, as well as the load.

When the switch is in the OFF-state, no current flows, during which a snubber circuit can act as a protection circuit to lower the amount of power lost due to parasitics. This also helps to increase the reliability of the device when operating in harsh environment conditions.

When the control voltage is affected by the load which is connected to the device, the VS-T70RIA60 features a circuit which helps maintain the same input control voltage independent of the load current. This ensures that the device can maintain operation even when the load current is higher than expected.

In summary, the VS-T70RIA60 is a two-stage switching device, designed to handle high-current capabilities and to provide both protection and isolation when disconnecting circuits and components. Furthermore, its ability to maintain the control voltage independent of the load current makes it suitable for a number of high power applications.
