Thyristors - TRIACs: BTA25H-800CW3G Application Field and Working PrincipleThyristors are electronic switching devices used in a wide range of applications, from power electronics to computing. TRIACs (Triode for Alternating Current) are a type of thyristor specially designed for alternating current operation.BTA25H-800CW3G is a TRIAC produced by Toshiba. It has a sensitive gate and is suitable for controlling circuits that require less than 800mA. It has a VCE (Collector-Emitter Voltage), of 400V and an IT (Peak On-state Current) of 0.8A.The BTA25H-800CW3G can be used in a wide range of applications, including LED lighting, motor control (such as fans, pumps, and other appliances), power switching, and surge suppressors. It is usually used in conjunction with an SCR (silicon-controlled rectifier), as well as other components, to allow for the regulation of electrical currents.To understand the working principles of the BTA25H-800CW3G, it is important to understand the four main stages of current it can produce: off-state, blocking, conduction and breakdown. In the off-state, the TRIAC is completely deactivated, and no current is able to flow through it. In the blocking stage, current can only pass through the TRIAC in one direction. This allows for the control of the overall current flow. In the conduction stage, current passes through the TRIAC in both directions, allowing for full current control. In the breakdown stage, the TRIAC is temporarily destroyed due to an excessive amount of current passing through it. The BTA25H-800CW3G also works by means of a gate current. A small current is fed into the gate to activate the TRIAC. As this current increases, the TRIAC will eventually allow for the passage of the overall current, with little to no control.The BTA25H-800CW3G is an incredibly versatile and reliable device. It is an ideal choice for any applications that require reliable alternating current control and regulation. Its wide range of applications and its robust design make it a popular choice for many engineers.
