Thyristors - SCRs - Modules

T820107504DH is a type of silicon controlled rectifier (SCR) module of the semiconductor thyristor family. It belongs to a group of switching devices that are controlled by a single electric current or voltage source and can be used to control large amounts of power. This particular device is a typical four-pin module package with a peak blocking voltage of 800V.

Application Field

T820107504DH is primarily used in applications that require efficient control of higher DC (Direct Current) voltage power and currents, such as solar inverters, battery chargers, industrial motor speed controls and similar. It offers greater efficiency, compared to other rectifier solutions.

This SCR module greatly reduces conduction losses, producing energy savings and enables much better heat dispersal, which can significantly reduce operating temperature. It is also used for medium frequency switching and phase control applications.The medium level control ensures less complexity in initialization, control and feedback.

Working Principle

Semiconductor thyristor modules such as T820107504DH use a gate, an anode and a cathode in order to control the flow of current in a circuit. By applying a voltage to the anode, the flow of current will increase until the maximum, or peak, threshold voltage is reached. This is known as the turn-on voltage.

The flow of current can then be controlled by applying a voltage to the gate. This will regulate the flow of current, preventing it from going above the maximum threshold. Adding a higher voltage to the gate will not have any effect on the current, as it already reached the maximum, so the voltage is only used to regulate and control the current, resulting in more efficient power management.

The importance of the cathode, or secondary terminal, is that it offers a degree of reliability and safety regarding the operation of the module. If the current flow in the circuit exceeds the configured peak blocking voltage, the module will shut down completely and the circuit will be protected from damage.

Conclusion

The T820107504DH is a great example of how a thyristor module can be used to efficiently and reliably control higher DC voltage power and currents. Using the gate and cathode terminals, this particular SCR can be used for a wide range of applications, such as motor speed controls, battery chargers and solar inverters. Thanks to its thermal properties, it can reduce total heat loss and improve overall efficiency.
