Thyristors - TRIACs: Q2016NH3RP Application Field and Working Principles

The Q2016NH3RP is a triac from a family ofthyristors, specifically designed for high-speed switching applications. It is a specialized device for controlling power in AC circuits and intended for device-level designs. It provides a maximum blocking voltage of 600V and is able to handle current levels up to 16A with a maximum power dissipation of 250W. It can be used in a variety of applications, including AC motor and industrial control, process and temperature control, lighting controls and other applications that require high-speed switching.

A triac is an abbreviation for a Triode Alternating Current switch, which is an heavily doped four-layer semiconductor device similar in construction to two SCRs connected in an inverse parallel configuration. Its three main electrodes are the gates, cathodes and anodes. By applying a gate voltage, the device can be switched on and off. The main difference between a triac and an SCR is that the former is able to control current in both directions, either in or out of the device. Therefore a triac can be used for both AC switching applications, as well as for devices that require bi-directional current flow.

Working Principles

To understand Q2016NH3RP’s working principles, it is important to note that a triac is essentially composed of two back to back SCRs. The main purpose of the device is to act as a switch in AC circuits and hence make the circuit controllable. In AC circuits, the electrons can flow in two directions and the triac effectively switches them on and off. An increase in gate current will turn the triac on, while decreasing the gate current will turn the triac off. The SCR attached to the triac will limit the amount of current flowing through the circuit, thus making the triac a more efficient device compared to the SCR.

Once turned on, the Q2016NH3RP will remain switched on even after the gate current is decreased. This is due to the memory effect of the device, meaning that the device does not have to be re-triggered for each half-wave. This is beneficial for applications that require continuous conduction of current in either direction.
