Q8015L5

Thyristors - TRIACs

The Q8015L5 is a TRIAC (Triode for Alternating Current) thyristor that controls both directions of the alternating current. It is suitable for applications requiring controlling medium-power AC circuits and higher switching speeds, such as in lamp dimmers, industrial heaters, small-motor controls, and other related applications, making it a versatile device that can be used in a wide range of fields.

Application Field

This TRIAC can be used in all kinds of AC switching applications such as light dimmers, motor controls, motor soft-start and stop, heating element controllers, lamp dimmers, and other kinds of AC switches. It is also suited for motor and heating element speed control and on-off switching; power factor correction; power distribution in the metering, protection and monitoring systems; lighting control; and thermal overload protection circuits.

Working Principle of the Q82015L5

The Q8015L5 is composed of three parts: the main thyristor (TRIAC), a gate control triac, and an integrated capacitor. The main thyristor is a silicon semiconductor device that is capable of switching and controlling the AC signal. This TRIAC is triggered by the gate control triac, which uses the integrated capacitor to reduce power consumption while still remaining effective. The integrated capacitor also increases the reliability of the TRIAC and helps control any surges in the AC signal.

The TRIAC consists of four electrodes connected to the gate, main terminal and the anode. When voltage is applied, the current flow from anode (A1) to main terminal (MT2) and the main thyristor switches on. The main thyristor begins to conduct current until the current exceeds the device’s rated value, when the device switches off. The gate control triac\'s integrated capacitor is then used to reduce power consumption and to help control any surges in the AC signal.

The Q8015L5 is a fast-switching TRIAC that is designed to switch AC voltage quickly and accurately. This makes it ideal for applications such as light dimmers, motor controllers, motor soft start and stop, heating element controllers, lamp dimmers, and other kinds of AC switches.

Advantages of the Q8015L5

The main advantages of this TRIAC thyristor are its fast switching capabilities and its ability to handle large currents. This device can switch AC voltage quickly and accurately, which makes it well-suited for applications requiring precise control of current flow in AC circuits. Additionally, it is immune to voltage transients and therefore can handle high inrush currents and operate at a higher switching frequency than comparable devices.

The Q8015L5 is also robust and reliable, since it has integrated protection from thermal overload and is completely encapsulated in epoxy resin. This makes it suitable for use in a wide range of environments, from industries to residential applications.

Conclusion

The Q8015L5 is a TRIAC thyristor device that is suitable for applications requiring precise control of medium-power AC circuits, such as in motor controllers, heaters, lamp dimmers and other related applications. It is fast-switching and is able to handle large inrush currents and voltage transients without any problems. Additionally, it is robust and reliable, making it suitable for a wide range of applications.
