Thyristors - TRIACs

A TRIAC (triode for alternating current) is a three-terminal electronic component used for controlling currents in alternating currents. The BTA312-800CT,127 is a new generation triac device that handles higher power loads with increased efficiency. It uses a proprietary design to maintain the stated maximum power level at high temperatures.

Applications
The BTA312-800CT,127 is a high-reliability, high-performance integrated-circuit device that can be used in a variety of applications such as AC power control, manufacturing, domestic appliances, lighting, motors, solenoids and other industrial equipment. It can also be used in temperature control equipment and medical diagnostics.

Working Principle
The BTA312-800CT,127 triac is triggered by the gate current and operates in both the positive and negative half cycles of the applied alternating current. The triac consists of three terminals: the Main Anode (MT1), the Main Cathode (MT2) and the Gate. MT1 and MT2 are the main electrical terminals, used for connecting with the load, between which the controlled current will flow. The Gate is the control terminal, and the Gate current controls the conduction of the device. When a positive Gate current is applied, a small voltage is dropped across the Gate and the triac is turned on. Once the main current has started flowing through the device, it will remain on until the voltage across the anode and the cathode drops to zero (the so-called “cutoff voltage”). The on-state power dissipation of the BTA312-800CT,127 is 600V/8A it has a low Gate threshold voltage of 2V.

The BTA312-800CT,127 has a wide operating temperature range of -40°C to 165°C, a high surge current rating of 20A, and a wide gate control voltage range of 0V to 18V.The BTA312-800CT,127 provides excellent performance over temperature and voltage variations. It has a high blocking voltage of 800V and a high triggering current of 0.7A for robustness and reliability. Furthermore, the BTA312-800CT,127 features an internal protection circuit that protects against over-temperature conditions and spikes.

In addition, the BTA312-800CT,127 has an I2t rating of 1.3 x 10-3A2s, which allows for fast load switching and excellent noise reduction capability. The triac is also RoHS compliant and is in conformity with the international quality standards. These features make the BTA312-800CT,127 suitable for a variety of applications, such as AC power controlling, heating, ventilating and air conditioning, fluorescent lighting and domestic appliances.

Overall, the BTA312-800CT,127 triac is an ideal device for high-power AC control applications. It features a low gate threshold voltage and a high blocking voltage, which ensures efficient AC power control, fast load switching, excellent noise reduction and improved reliability.
