Thyristors - TRIACs form an important and versatile class of power electronic semiconductor devices. The common TRIAC device is a three-terminal alternistor that is triggered by a single gate current into conduction. TRIACs are useful in AC as well as DC circuits as they can control both half-wave and full-wave AC currents. The BTA12-800BWRG is a TRIAC specifically designed for power andload switching applications, with an insulation voltage rating of 800V, a current ratingof 12A, and a thermal dissipation rating of 25W.

BTA12-800BWRG Application Field

The BTA12-800BWRG is typically used to switch either AC motors or inductive loads like heating elements and lamps. This device can also be used in applications requiring high input immunity, such as controlling the current in battery-powered devices, or in digital consumer applications like microwave ovens, electric fans, and power tools. Moreover, the BTA12-800BWRG can be used in applications requiring fast switching, such as motor speed controls.

BTA12-800BWRG Working Principle

The BTA12-800BWRG is a bidirectional semiconductor switch, meaning that it can control both positive and negative current flow. This switch is constructed with four PNPN layers in a single package, and these four layers are connected in such a way that anode and gate terminals form an in-built trigger wheel. When the gate voltage is applied, the trigger wheel sets off a circulating current between the anode and cathode that results in current conduction between the anode and cathode. When the gate voltage is removed, the trigger wheel ceases to circulate, and the conduction between the terminals ends.

In terms of power control, a TRIAC switch like the BTA12-800BWRG can be used to control the power supplied to a load. For example, the BTA12-800BWRG can be used to control the speed of an electric motor by turning it on or off at certain stages of the AC supply. By varying the amount of time that the TRIAC switch is active and inactive, the power supplied to the motor can be appropriately regulated.

The BTA12-800BWRG is a handy and versatile device, and it is easy to use. As long as the proper current and voltage ratings are observed, this device will provide reliable switching and power control in electronic circuits.
