Thyristors - TRIACs

BCR12CM-12LB#BH0 is a kind of thyristors among TRIACs. A TRIAC, or Triode for Alternating Current, is a solid state AC switching device comprised of two thyristors that can control AC voltages and currents. According to the application field, the BCR12CM-12LB#BH0 is mainly applied to the lighting control systems and air conditioning motors, etc. Moreover, within the frequency of 30 Hz to 400 Hz, it can be used in motor control and other circuit fields. Now let\'s see the working principle of the BCR12CM-12LB#BH0.

Working Principle

As mention above, BCR12CM-12LB#BH0 is a two thyristors switching device with a breakdown voltage at 400V (max). When the current which is the same positive polarity phase of the power supply passes through the main terminal of the device, then current flows through the anode and ionizes the gas, which makes the electrons and ions recombination, to turn on the device. Meanwhile, when the negative polarity phase current flows through the anode, the TRIAC device also turns on. To briefly explain the process, the n-type and p-type material on the semi-conductor get recombined to form the avalanche diode and flow along the anode current path. In conclusion, the BCR12CM-12LB#BH0 conducts current in either direction when it is triggered.

Hermetical Seal

In order to keep BCR12CM-12LB#BH0 away from being oxidized and other influences, hermetical seal is also necessary. What\'s more, the leakage current is less than 10μA and the insulation resistance level is more than 500MΩ. This makes the device does not get interference from the environment, which can guarantee the normal working of the device.

Heat Dissipation

Heat dissipation is also important when talking about the TRIACs. The power dissipation on the BCR12CM-12LB#BH0 is 0.07W and the maximum temperature of the device surface is 150°C. The device can tolerate 2KV surge voltage under the air pressure. Besides, with the correct heat sink, the working value of the device won\'t influence by other parts.

Conclusion

The BCR12CM-12LB#BH0 can be applied in many fields according to its working principle, hermetical seal, and heat dissipation. Through the working process, it can control the AC current and voltage within the frequency of 30 Hz to 400 Hz. What’s more, the quality is guaranteed when taken the hermetical seal into consideration. In addition, the device can extremely tolerate the temperature with the help of the heat sink.
