Thyristors are semiconductor devices which are commonly found in most electronic power circuits. In particular, TRIACs are a type of thyristor which is widely used as a switch or rectifier in alternating current power circuits. The Q8016RH3 is a TRIAC which offers excellent electrical and thermal performance. It is highly efficient, providing low losses and higher gains than other TRIACs.

The Q8016RH3 is a medium power TRIAC which is suitable for applications in the range of 1A to 16 A.¹ It is commonly used for line-operated motor drives and lighting applications where medium levels of control are required. The device is also used as anlighting dimmer switch, as it has a fast turn on response and can be used to rapidly dim lights.²

The operating principle of the Q8016RH3 is based on controlling the current through the device. The device has three terminals - Main Gate, Auxiliary Gate and Gate Trigger. The Main Gate provides essential current control while the Auxiliary Gate adds extra control or protection.³ The Gate Trigger is used to control the gate current and thus the switching of the device. When triggered, the device conducts electric current only in one direction. This direction is determined by the gate current.

The main feature of the Q8016RH3 is the on-state voltage drop, which is rated at 4V, making it one of the lowest drop TRIACs available.⁴ This makes the device particularly suitable for applications where high efficiency is essential. Other features include a high trigger current, a high surge capability and a fast turn on response.⁵

In conclusion, the Q8016RH3 is an excellent choice for medium power switching and control applications which require high efficiency and low losses. Its features make it suitable for a variety of applications such as motor drives, lighting and dimmer switch applications.
