Thyristors - TRIACs: QJ6016NH6RP Application Field and Working PrincipleThyristors are solid-state semiconductor devices which are used to control the current in a circuit. They’re primarily used in circuit protection, power control, and power conversion applications, and regular Thyristors are known as bipolar thyristors because they’re comprised of two terminals and a control gate. Triacs are a special type of thyristors that enable current to be switched in both directions. These devices are often referred to as bidirectional thyristors and are used to control the current flow in both directions.The QJ6016NH6RP is a 600V, 16A TRIAC device. It has a maximum on-state voltage drop of 1.5V, making it suitable for applications that require low losses when conducting. This device is designed to be used in applications such as heating, home appliances, and lighting control.The core of any TRIAC is the basic thyristor construction. It consists of two PN junctions that can be in either an on or an open-state depending on the voltage level on its control gate. Both PN junctions are connected in a series arrangement, with the P and N junctions being back to back parallel to each other. The two junctions are connected in a way that opposite directions of current flow can pass through them when the triac is in the on-state.When the gate of a TRIAC is triggered with the proper signal, it turns on and allows current to flow from its anode to its cathode. This signal is known as the "gate trigger current" and it is enough to keep the triac in the on-state even when the voltage across it is zero. Once the gate trigger has been applied, the triac can continue to remain in the on-state even if the voltage across it reduces to a level that is much less than the initial gate trigger current.The QJ6016NH6RP is an ideal device for applications that require precise current control and switching in both directions. Its gate trigger is designed to trigger at low enough voltage levels, ensuring that the TRIAC will remain in the on-state even when the voltage is reduced to a level lower than the gate trigger voltage. This makes the device suitable for applications in which precise triggering and current switching is required.In applications such as home appliances, once the gate of the TRIAC is triggered with a proper signal, the device can remain in the on-state even if the current increases or decreases. This eliminates the need for any additional electronic control for switching purposes, reducing the overall system complexity.Overall, QJ6016NH6RP is an ideal device for a variety of applications, such as controlling the current flow in both directions in applications that require low losses when conducting, such as home appliances, heating, and lighting control. Its low on-state voltage drop and precision current switching capabilities make it suitable for many applications where current and voltage need to be monitored and controlled accurately.
