TRIAC, also known as three-terminal triode thyristor, has been widely used in electrical control and power electronics since 1950s. The Q4015LTH is a specific type of TRIAC. It is a sensitive PNPN thyristor gate with a maximum gate power rating of 500mW.

The Q4015LTH is best suited for a variety of applications from 200 to 600V designed for applications in building control, motor, electronics and electrical control systems. It is typically used as a switching device in power control applications, such as controlling light dimmers and fan speed controllers. The Q4015LTH also offers superior long-term reliability for motor and other power control applications.

The working principle of the Q4015LTH is that when a positive gate current is applied to it, it acts as an exclusive-OR circuit with two thyristors connected in series. When there is an insufficient current, the thyristors remain in the off position and turn off the circuit. When a sufficient current is applied, the thyristors turn on the circuit and function as a single switch. In addition, when current is applied to the thyristor gate, it is also able to detect weak signals, using the intrinsic positive threshold gate-triggering characteristic of the device.

The Q4015LTH offers a wide range of benefits. It is reliable, providing long-term durability for motor and other power control applications. It is also accurate in detecting weak signals, allowing it to be used in a variety of applications from 200 to 600V. Lastly, it is easy to install, and once installed it requires no additional maintenance.

The Q4015LTH is a reliable and easy-to-use device for controlling and regulating electrical loads, making it an ideal choice for motor and power control applications. Its wide range of benefits ensures quality control for a variety of applications, making this device suitable for both domestic and commercial applications.
