Thyristors - TRIACs is a category of devices that are widely used for power control and switching applications. They are capacitive and resistive loads and can handle high current and power levels. TRIACs, also known as TRIode for Alternating Current, are a type of thyristor which are widely used in the industrial equipment and consumer electronics. They are a bilateral switch with three terminals (comprising of an Anode, Gate and Cathode), which can control both positive and negative polarity of current.

A Q8012LH5, is a TRIAC manufactured by Aerovox which is suitable for use in low power AC switching applications. It has a maximum Current at 35A and can operate at Voltage of 400V RMS and 600V peak. It is suitable for use in lighting, industrial and consumer applications with wide variety of equipment.

The Q8012LH5 TRIAC works on the principle of a bi-directional thyristor. When a voltage is applied to the Gate terminal, a layer of negative charge carriers are formed in the base region between the Anode and Cathode, which leads to the saturation of the junction. When the Gate voltage is increased to a certain level, the conduction of current takes place and the current flows from Anode to Cathode in both directions.

The Q8012LH5 TRIAC can be used for various applications such as power factor correction and controlling lights and motors. It is used for controlling the voltage supply to the motor and thus providing variable speed operation to the motor. It is also used in other consumer electronic applications such as dimming lights, time delay OFF and time delay ON operations, fan and pump control, etc. It can be used in power factor correction circuits, static and dynamic switches and solid-state relays.

The Q8012LH5 is a sensitive gate TRIAC and it responds quickly to gate signals. It has an excellent overload protection and it is also thermally stable. Its package includes heat sink to dissipate thermal energy and includes a built in snubber circuit which protects it from electrical overstress.

The Q8012LH5 is also a cost effective device with robust construction and low switching losses. It is easy to install, maintain and troubleshoot. Its cost effective design and high performance make it perfect choice for various AC applications.
