Thyristors - TRIACs are a type of semiconductor component that control the current flow with the help of a triggering voltage. The QK015L5 is a special type of thyristor that is built with a bidirectional triode for alternating current or, (TRIAC.) This type of component is made with a three-terminal device, capable of controlling the current in two directions.

The component is mainly used in lighting and motor control circuits, as well as in induction heating applications. However, its strong current control capabilities make it suitable for other control circuits as well. In comparison to other types of thyristors, TRIACs are often used as a replacement in simpler circuits, as they are more efficient and affordable than many other versions.

The QK015L5 component works in two stages. The first stage is referred to as the forward blocking stage, where the component is reverse biased. This means that the junction voltage is higher than the source voltage and charge can not enter the device. The secondary stage is referred to as the forward conduction stage. This is the process where the output voltage is higher than the input voltage, enabling charge to flow through the thyristor.

In both stages, the triggering voltage is used to change the biasing state of the component and allows the current to flow through the device. In the forward blocking stage, the voltage of the gate terminal is lower than the voltage of the anode terminal and the current is blocked. In the forward conduction stage, the voltage of the gate terminal is higher than the anode terminal and the current can pass through.

The QK015L5’s three-terminal design makes it an ideal component to regulate the current flow, in both directions. It can be used to replace single-directional thyristors as it can control the current in two terms. The component has excellent temperature and surge current performance, as well as a wide operating range of -50°C to 105°C.

The QK015L5 component is mainly used in lighting and motor control circuits, as well as induction heating applications. Its strong current control capabilities make it suitable for various control circuits, such as HVAC, air conditioners, power supplies, and power switches. Due to its efficient and affordable feature, TRIACs are often used as a replacement for single-directional thyristors.

In summary, the QK015L5 is a special type of three-terminal device that is built with a bidirectional triode and is mainly used in lighting and motor control circuits, as well as induction heating applications. Its strong current control capabilities make it suitable for various control circuits such as HVAC, air conditioners, power supplies, and power switches. It works in two stages: the forward blocking stage and the forward conduction stage, and the triggering voltage is used to allow the current to flow through the device.
