Thyristors - SCRs (Silicon Controlled Rectifiers) are a type of semiconductor device that are used for controlling electrical current. The T507068054AQ is a type of SCR specifically designed for high current applications. This article will discuss the application field and working principle of the T507068054AQ.

1. Application Field

The T507068054AQ SCR is primarily used in power electronic applications. It can be utilized in high current applications, such as motor control, soft starters, welding, UPS and lighting systems. Its applications in high power circuits necessitate the SCR’s excellent performance in controlling, regulating and switching the large currents.

The T507068054AQ is an ultrafast SCR capable of carrying a peak surge of up to 500 amperes, with a range of 400mA to 600mA. It offers a breakdown voltage of 25V, a typical forward voltage drop of 1V and an operating temperature range between -40˚C to +125˚C.

It is made of high quality, low-on-resistance and low inductance MOS (Metal Oxide Semiconductor) chips that enjoy long life and excellent electric characteristics.

2. Working Principle

At its simplest level, an SCR is a two terminal device that acts as a switch. The gate control terminal can control the current flow by turning on and off the main current path between the anode and cathode. The SCRs gate control is very sensitive and can be triggered with a low voltage signal.

The T507068054AQ SCR is a three terminal device because it contains an additional Gate terminal that can be used to control the SCR gate voltage. This gate voltage must be larger than the anode voltage in order to be able to trigger the turn-on action. When the two voltage levels are balanced, the SCR is said to be in a ‘non-conducting’ state and the resulting device is referred to as the ‘off’ state.

The SCR is triggered into a ‘conducting’ state when the gate voltage exceeds the anode voltage. This is what allows the T507068054AQ To act as a switch. When this happens, the device is said to be in its ‘on’ state and current flows through the SCR.

The SCR can be turned off again by significantly reducing the gate voltage below the anode voltage or, in some cases, by increasing the anode voltage, up to the breakdown rating of the SCR. This process of turning the SCR off, by reducing the gate current is referred to as ‘comparator’ mode.

3. Conclusion

The T507068054AQ Is a specific type of SCR specifically designed for high current applications. Its applications in power electronics make it ideal for motor controls, soft starters, welding, UPS and lighting systems. The working principle behind SCRs involves the use of a gate control terminal that can be triggered with a low voltage signal to turn the SCR on and off. With its excellent electric characteristics and long life span, the T507068054AQ has become an essential device in the power industry.
