Thyristors - TRIACs

A TRIAC is an abbreviation of a three terminal ac (Alternative Current) switch. It is a solid state device, meaning that it is composed mostly of semiconductor material, usually silicon. It is used in AC circuits when it is necessary to periodically switch the current on and off or to dimmer a controlled current. The QJ6025RH6TP is a specific type of TRIAC that has been specifically designed for applications in which controlling the amount of current flowing through is necessary.

Application Field

The QJ6025RH6TP is installed in many settings where controlling the current flow is essential. It can be primarily found in automated manufacturing processes where its ability to switch off and on quickly makes it a useful tool. In addition, due to its integrated function and safety standards it is often used in medical settings. These can include such settings as operating rooms and labs, where a range of voltages needs to be controlled.

In addition, this type of TRIAC is also immensely useful in settings such as lighting solutions. It is used in both commercial and residential installations where controlling the amount of light emitted is necessary. This TRIAC is a reliable and safe solution where dimming light is a requirement.

Working Principle

The QJ6025RH6TP TRIAC operates using a simple structure. It is capable of detecting when a current is flowing in the circuit and initiating an action the moment the voltage rises above a certain threshold. The amount of switch happening is directly proportional to the amount of current passing through. To achieve this, the device features an integrated three pin gate electrode. This, together with a dual anode-gate valve makes this device ideal for dimming.

Once the voltage is applied, the gate begins to flow, filling up the channels of the device. This, in turn, causes an initial rise in the flow of electrons which triggers a metal-oxide-semiconductor conduction. This results in an increase in the flow of electrons and current, eventually creating a full-fledged AC bridge.

An additional feature of the QJ6025RH6TP is the inclusion of self-triggering and restarting protection mechanisms. The current flowing through the circuit triggers the device, while the included temperature and surge protection mechanisms prevent the device from stabilizing and resetting. This is important, as these protection mechanisms keep the device running at a stable current level. If a surge in voltage is detected, the device will not become destabilized, as it automatically switches off, keeping the current in check.

The QJ6025RH6TP is a powerful TRIAC with a wide range of applications. Its simple yet effective structure makes it a reliable solution for installations requiring precise control of the current and help prevent dangerous overloads.
