QK010LH5

Thyristors are semiconductor devices that are commonly used in electrical applications. One type of thyristor is the TRIAC, a three-terminal, three-layer electronic device with similar characteristics to two back-to-back SCRs. The TRIAC has alternating polarities from each of its three terminals, thus enabling it to be used as a switch, allowing current to flow in both directions when triggered. One particular product of the TRIAC family is the QK010LH5.

The QK010LH5 is a Bidirectional Thyristor with a holding current of 10A, a maximum trigger off-state voltage of 800V, and an on-state voltage of 1.6V at 10A. It has a surge current rating of 25A and a maximum on-state current of 10A. It has a thermal resistance of junction-to-case of 5.6K/W and a maximum junction temperature of 150℃.

The QK010LH5 is typically used in light dimmers, line switching, motor control applications, and AC switches. It is suitable for induction-cooking and charging control applications as well. This device is built using advanced technology to ensure that it can operate safely and efficiently within normal and fault conditions. It has a high thermal resistance and a low forward voltage drop, making it more efficient and reliable than other TRIACs.

The working principle of the QK010LH5 can be easily explained. When a signal is applied to the gate, the TRIAC switches on and current begins to flow from the MT2 terminal and then returns back to the MT1 terminal, enabling current to flow in both directions. Once the gate current is no longer present and the threshold voltage of the TRIAC is exceeded, the TRIAC switches off, restricting the flow of current. The amount of current which passes through the TRIAC is regulated by the applied gate signal, allowing for precise control in applications.

The QK010LH5 is a reliable, efficient, and cost-effective solution for various electrical applications. It is capable of handling high-currents, while providing precise control and high thermal resistance, making it suitable for use in a variety of applications. Its robust construction and unique properties make it a great choice for a wide range of applications.
