Thyristors are solid-state electronic components that are used to control and manage electric current. TRIACs stands for TRIode for AC and are a three-terminal electronic device used for controlling electrical current in an AC circuit. The Q2008DH3TP is a high power, four-terminal Triac that is specifically designed for various switching, controlling and protection in lighting applications.

The Q2008DH3TP has a maximum blocking voltage of 800V (V DRM) and its junction temperature can reach up to 150°C. It features a 500µA on-state current (I T(RMS)) and a peak surface mount package of SO-8. Its maximum operating temperature is 125°C and its forward gate current requirement is 5mA.

The Q2008DH3TP is designed for applications such as lighting, industrial motor control and heating, as well as domestic appliance control and power supply. Its applications in the lighting sector include general lighting, commercial lighting, and fluorescent lighting. Additionally, its applications in industrial motor control and heating include heating of fans, water pumps and other motors.

The Q2008DH3TP device works by absorbing a signal that is sent through its Gate terminal. When activated by the signal, it triggers the Triac which then allows the AC current to flow through its Main and Auxiliary terminals, thereby activating the device while simultaneously blocking all signal other than the one it has received.

It is important to note that the Q2008DH3TP requires a voltage between 10V and 30V and a current over 5mA to ensure its Gate completes the turn-on process. Moreover, it is also important to keep in mind that the output voltage is dependent on the Gate voltage, meaning that the output voltage may vary if the Gate voltage is varied.

In order for the Q2008DH3TP to enter its blocking state, the anode voltage must be higher than the Gate voltage. In this state, the device is considered to be ‘on’ and will draw current from the mains supply. It will not, however, draw any current when the anode voltage is equal to or less than the gate voltage, as this indicates that the gate has been off and the device is deactivated.

In summary, the Q2008DH3TP is a four-terminal Triac that is specifically designed for applications such as lighting, industrial motor control and heating, as well as domestic appliance control and power supply. It has a maximum blocking voltage of 800V (V DRM), a junction temperature of up to 150°C and a peak surface mount package of SO-8. It requires a voltage between 10V and 30V and a current over 5mA to ensure its Gate completes the turn-on process. The device works by absorbing a signal that is sent through its Gate terminal and allows the AC current to flow through its Main and Auxiliary terminals when activated.
