Q6016RH657

Thyristors - TRIACs

A Thryristor - TRIAC, sometimes referred to as a Thyristor, is a three terminal semiconductor switch that is used in a variety of electric power switching applications. The name TRIAC stands for Triode for Alternating Current. The TRIAC\'s basic function is to open and close the electric circuit as needed to control the flow of current. With this electric switch, it is possible to 0control the amount of current, as well as the direction of the current in a circuit.

Q6016RH657 Application Field and Working Principle

The Q6016RH657 is a Thyristor - TRIAC manufactured by Fairchild Semiconductor. It is designed for an operating temperature range of 0°C to 70°C and for a maximum operating voltage of 500 volts. The Q6016RH657 Thyristor - TRIAC is particularly suited for high voltage applications, such as a power supply or motor speed control circuit. It is also suitable for use in zero cross switching, temperature controllers, AC control circuits and various other applications.

The Q6016RH657 is a unidirectional thyristor switch, enabling the current to flow in only one direction. The switch has three terminals, namely an anode, a gate and a cathode. The anode is the positive terminal, while the cathode is the negative terminal of the switch. The gate terminal is the control terminal which controls the on and off of the switch. By applying a gate current of at least 1.5mA to the thyristor - TRIAC, the electric current will flow in the desired direction until the gate current is removed from the thyristor - TRIAC. It is important to note that the gate circuit must be a separate circuit from the one being switched.

In addition, the Q6016RH657 is manufactured using a highly reliable, robust and advanced “T” structural thyristor (Triode for Alternating Current). This type of Triode is composed of a semiconductor material (e.g. silicon) and has a PNPT structure, which means that its three terminals are connected in a triangular fashion by the sides of the semiconductor material. This kind of arrangement makes possible the controllable bidirectional current flow.

The thyristor - TRIAC Q6016RH657 also has an additional feature called Quadrant Operation. This feature allows the current to flow in any one of the four quadrants of the AC waveform. This feature is particularly useful in applications where controlling or regulating AC power or voltage is required, such as in motor speed control circuits or in temperature controllers. The four quadrants of operation can be selected by simply connecting one of the four terminals (1, 2, 3 or 4) of the thyristor - TRIAC to the appropriate AC terminal.

In conclusion, the Q6016RH657 Thyristor - TRIAC is a versatile and reliable switch suitable for a variety of applications where the flow of electricity needs to be controlled, including motor speed control and temperature regulation. It is easy to install and has a highly reliable, robust and advanced “T” structural thyristor. Additionally, its Quadrant Operation allows the current to flow in any one of the four quadrants of the AC waveform.
