Thyristors are a type of semiconductor device, commonly used in a wide range of applications, including power switching and electrical power control. A thyristor is a type of switch that can either be on (completely conducting) or off (completely non-conducting). It is also referred to as a “controlled rectifier” or a “solid-state switch”.One of the most common types of thyristors is the TRIAC, which is an acronym for Triode for Alternating Current. A TRIAC is a device composed of two thyristors, connected back-to-back, that allows current to flow in either direction. This characteristic makes it well suited for controlling alternating current (AC).The Q4025LH5 is a TRIAC used for controlling AC power in industrial, commercial, and consumer applications. It is a four-pin device, with a gate connection for controlling the current and a pair of cathode pins for detecting current flow.The Q4025LH5 is designed to be used in applications where high gate current is required to switch on the TRIAC. It has a current rating of 2 Amps RMS and a voltage rating of 400 Volts. It is designed to be used in applications such as LED lighting, HVAC, motor control, and household appliances.The working principle of the Q4025LH5 is relatively simple. When a signal is applied to the gate connection, the device will switch on and allow for the current to flow between the two cathode pins. This switching on of the TRIAC will occur if the gate current is sufficient and the voltage across the device is above its firing voltage. To turn off the TRIAC, the gate current is removed, causing the device to then switch off.In addition, the Q4025LH5 is designed to be highly reliable and noise immune. It features a fast response time and low gate current requirements. Overall, the Q4025LH5 is an ideal choice for applications requiring low gate current switching of AC power. It is highly reliable, has a long lifetime, and provides noise immunity. Therefore, it is suitable for applications such as LED lighting, HVAC, motor control, and household appliances.
