Thyristors - TRIACs play an essential role in the study and application of AC power control. The BCR16CM-16LH#BH0 is a three-pin bidirectional DC switch with two gate terminals, two main terminals and a third junction terminal. It is used mainly for AC control applications such as lamps, heater, light dimmers, and motor speed control. In this article, we will discuss the application field and working principle of BCR16CM-16LH#BH0.

Application Field

The initial application field of BCR16CM-16LH#BH0 was for household AC light dimming and motor speed control. The BCR16CM-16LH#BH0 device can be used in a wide range of applications and is suitable for AC control systems that are powered from 110V to 240V AC mains. The device can also be used in low voltage AC/DC converters, professional lighting systems, fans, and pumps. It is also applicable in H V AC/DC control systems like home appliances, industrial control systems, and power electronics.

Working Principle

The BCR16CM-16LH#BH0 is a three-terminal device consisting of two gate terminals and two main terminals. The gate terminal voltage controls the thyristor triggering current, while the main terminal voltage supplies the current to the load. The three-terminal junction is connected to the gate and main terminals. When a forward or reverse voltage is applied across the main terminals, a regulated current starts to flow through the load and the entire circuit. The device operates on the principle of a latchup: when the voltage is applied to one of the gate terminals, it triggers a forward current in the main circuit. If the current drops below a certain level, the device latches off and the current turns off. The latch will remain open until the voltage is reversed. Upon reversal of the voltage, the latch will close and the current will flow through the device. This switching is known as thyristor commutation.

The BCR16CM-16LH#BH0 is also suitable for working with variable speed drives for controlling motors. The device is also used as a switch in electronic circuits for turning on and off of medium and low power circuits. It can also be used in other applications like controlling audio and video transmission, controlling light emitting diodes (LEDs), switching AC loads and coupling high power AC signals.

Conclusion

In conclusion, the BCR16CM-16LH#BH0 is an important device in AC control systems. The device is suitable for application fields like lamps, heater, light dimmers and motor speed control, as well as home appliances, professional lighting systems and power electronics. The device works by the principle of a latchup, wherein a controlled current starts to flow through the load and the entire circuit when a forward or reverse voltage is applied across the two main terminals. The latch will open and close upon reversal of the voltage and current will flow through the device. This device is often used for controlling audio and video transmission and switching AC loads for medium and low power circuits.
