Thyristors - TRIACs

A TRIAC is a type of thyristor, which is a specialized semiconductor device with three terminals and one gate. BTA316X-800B,127 is a type of TRIAC, it is widely used in residential and commercial AC power applications. This article will provide an overview of BTA316X-800B,127\'s application fields and working principle.

Application Field

BTA316X-800B,127 is widely used in manual and automated lighting control, heating and cooling controllers, machinery AC motor control, and other low power electrical supplies. It features fast turn off and on times, low forward and reverse current leakage, and low thermal resistance. This product is also suitable for use in a wide range of temperature extremes, which makes it a great choice for any application.

Some key applications of BTA316X-800B,127 include residential AC motor control, heating and cooling controllers, door locks, refrigerator compressors, wall and ceiling fan controls, and more. It is also applicable for use in professional AC motor control, high-power lighting controllers, and high power AC motor control.

Working Principle

BTA316X-800B,127 works by using two transistors connected to form two half-controlled rectifiers which both conduct alternately depending on the control signal. When the control signal applied to the gate exceeds a certain threshold, one of the two half-controlled rectifiers starts to conduct and will continue to do so until the current drops below the level set by the control signal. This means that the current will flow in both directions once the gate voltage exceeds the set threshold.

When the gate voltage drops below the set threshold, the current will stop flowing and the other half-controlled rectifier will start to conduct. In other words, BTA316X-800B,127 will switch off and carry current only when the control signal is present. This feature makes it convenient for applications such as motor control, where the current needs to be switched off and on as required.

The switching ON and OFF of BTA316X-800B,127 is done by the voltage and current conditions of the control signal applied to the gate. This means that the current and the voltage of the control signal are the main parameters which affect the triggering of BTA316X-800B,127. Additionally, when the voltage of the control signal exceeds the threshold, the current of the switch will flow in both directions.

BTA316X-800B,127 can withstand a maximum current of 3A and a maximum voltage of 800V in continuous mode. It is also available in various consumer and industrial versions, which have different current limits based on their construction.

Conclusion

BTA316X-800B,127 is a type of TRIAC, which is a specialized type of thyristor used in many AC applications. It is notable for its fast turn off and on times and low forward and reverse current leakage. BTA316X-800B,127 is widely used in manual and automated lighting control, heating and cooling controllers, machinery AC motor control, and other low power electrical supplies. Its working principle is dependent on the control signal applied to the gate, and it can withstand a maximum current of 3A and a maximum voltage of 800V in continuous mode.
