Q2004V4TP

Thyristors - TRIACs

A TRIAC, or Triode for Alternating Current, is a type of thyristor that is widely used in switching and control applications. It is a solid state device composed of a semiconductor material that can be triggered by an applied gate voltage. The gate voltage controls the flow of current through the device and the output of the TRIAC can be used to control the load connected.The TRIAC is an important and versatile electrical component for both commercial and industrial applications. It is used for controlling AC loads such as heating and lighting, as well as for switching in control circuits. The TRIAC also has the capability to act as an AC switch and provide control of the AC load. This makes the TRIAC an excellent choice for applications requiring power reduction and load control.

Q2004V4TP application field and working principle

The Q2004V4TP is a TRIAC, a three-terminal AC switch, which can effectively turn AC power on and off. It is designed for use in AC power control circuit applications ranging from simple manual switches to electronic controls such as motor controllers. The Q2004V4TP is rated at 400V and a maximum current of 4A.The Q2004V4TP operates on the principle of a thyristor, an electronic switch. A thyristor is a three-terminal electronic switch that is turned on when a voltage is applied to its control electrode. The current is then allowed to flow in the direction of the applied voltage, thus controlling the AC load. This is different from a mechanical switch, where the direction of the current must be reversed in order to turn it off.The Q2004V4TP is composed of a high quality, temperature-resistant ceramic body and a robust electrode-providing structure that ensures long-term operation. The device is designed to be used in both indoor and outdoor environments and is resistant to extreme temperatures and humidity. The device also features built-in diodes for reverse current protection, eliminating the need for external components The Q2004V4TP provides a high switching speed (2ms) and a low ON resistance (1.0 Ohms). This offers an efficient and reliable way to control AC power flows in various applications. As a TRIAC, the device can also be used in conjunction with a timer or the control of an AC motor. The Q2004V4TP is a versatile component that is suitable for a variety of applications such as lighting control, heating control, and appliance control.
