Thyristors, also referred to as silicon-controlled rectifiers (SCR), are three-terminal devices constructed from two or more layers of semiconductor materials stacked upon each other. When correctly biased, the thyristor can latch-up, meaning the device will remain in the conductive state indefinitely, until the current flows in the opposite direction. A TRIAC is just a type of thyristor, meaning it has the same basic construction and function, but with three terminals instead of just two.

The Q2016NH3TP is one such example of a TRIAC. It is specifically designed as a low-power switch with a maximum off-state current of 1μA. It has a breakdown voltage ranging between 26V and 40V, and an on-state voltage drop of only 1.4V. The device also features a low-power activation curve that helps to reduce the power requirements for switching applications.

The Q2016NH3TP find applications in the controlling of low-power loads, such as in the controlling of heated resistance elements or small LEDs, or in other low power applications. The device is also used as a switch for controlling motor speed or direction. In this type of application, a zero-cross detector is employed to ensure that the TRIAC does not turn on until the voltage drops to zero.

The operational principle of the Q2016NH3TP is based on the capability of the device to respond to gate current in order to turn the device on, and maintain the current until the gate drives current in the opposite polarity. When the TRIAC turns on, the current passes through the device until the voltage reaches the breakdown voltage. At this point, the device will break off, meaning the current breaks down. This is known as the snapback effect.

Once the TRIAC has turned on, the current will continue to flow until the applied voltage is below the working voltage. This means that the device can still maintain its on-state even when the voltage drops to its zero-crossing point. This makes it ideal for controlling the current of small loads.

The Q2016NH3TP also features a relatively low latching current of 20mA. This means that the device requires less current to remain in the on-state than other TRIACs. This makes it possible to control even smaller loads, such as delicate computer chips, with minimal power requirements.

The Q2016NH3TP offers many advantages over other TRIACs, including the ability to be used in low-power applications, adequate breakdown and on-state voltages, and a low latching current. All of these features make this device an ideal choice for many low-power switching applications.
