Thyristors - TRIACs refers to a semiconductor component which is mainly used for controlling the power. Thyristors - TRIACs has different types such as BTA12-800CW3G, the application and working principle of it will be introduced from the following.

Firstly, the BTA12-800CW3G is a TRIAC thyristor with 800V 12A. The typical applications of it including phase-control and on/off control, like booster power supply, heater, fan and home appliance, etc.

Secondly, as to its working principle, in the conduction both forward-mode and reverse-mode, the BTA12-800CW3G can provide symmetric, controllable power switches. The surge withstand voltage is up to 1.3KV, the average on-state current is 12A and the average off-state current is 10mA.

Then, in the on-stage, BTA12-800CW3G can be triggered with gate currents significantly lower than the holding current, it has been optimized for AC power switches especially for applications under 150Hz. Furthermore, for the gate stack size, it is reduced by half compared with similar TRIAC products in the market. It also shows strong protection capability against shorted load, open load, overvoltage, overcurent and power surges, as well as providing high reliability, extreme long term stability and highly repeatable performance.

Next, the thermal-shutter characteristic of BTA12-800CW3G enables a high thermal rating without the need for a fuse or switch. The on-state power rating of the device is 96W, with a peak surge rating of 3KW. What’s more, the integrated ESD protection protects the device from most kinds of electrostatic discharges.

Lastly, BTA12-800CW3G can quickly break the conduction within only 10μs, even when the AC circuit is still conducting. The high break-over current can help to reduce the reverberation when breaking the conduction, reducing the overall interference to other components. And its extreme low triggering current can help to reduce the input power in the application.

In conclusion, BTA12-800CW3G belongs to Thyristors - TRIACs, it is widely used in phase-control and on/off control. Its working principle emphasizing high efficiency, low voltage and fast responding, as well as its protection capabilities which guarantee the high reliability, making it a perfect choice for applications such as booster power supply, heater, fan and home appliance.
