TRIACs, or thyristors, are electrical switches which can control the on/off flow of current in both directions. TRIACs allow a single part to be used where previously two parts such as a diode and transistor were required. They are typically used in light dimmers, speed control and motor control applications. In this article, we will look at one particular TRIAC, the BCR4AS-16LH#B00, and discuss its application fields and working principle.

Application Fields

The BCR4AS-16LH#B00 TRIAC is used in low voltage and low power control applications that require high-speed switching in both directions. It is ideal for use in light dimming, AC motor speed control, and other high-speed switching applications. This TRIAC has a maximum voltage of 400V and a maximum current of 16A, which makes it suitable for use in a range of light dimming, motor control, and other power control applications.

Working Principle

The BCR4AS-16LH#B00 TRIAC is a bidirectional semiconductor device with two SCRs connected on either side of its middle. When two control signals are applied to its gate, it can switch on and off current in both directions. When the control signals are applied to the gate, they turn the TRIAC on and allow current to flow between the anode and cathode. When the control signals are removed, the TRIAC switches off and no current is allowed to flow.

The control signals must be of opposite polarity in order to turn the TRIAC on and off. This is done to ensure that the TRIAC can switch on and off current in both directions, as one control signal will turn the TRIAC on and one control signal will turn it off. The control signals must also be applied for a minimum of 750ns in order to ensure that the TRIAC switches on and off properly.

Conclusion

The BCR4AS-16LH#B00 TRIAC provides a reliable and efficient means of controlling current in both directions. It is used in light dimming, AC motor speed control, and other high-speed switching applications. Its duty cycle and control signals must be carefully managed to ensure that the TRIAC switches on and off properly in both directions. In summary, the BCR4AS-16LH#B00 TRIAC is a reliable and efficient device for controlling current in both directions.
