Thyristors - TRIACs

A TRIAC, or triode for alternating current, is a semiconductor device used for controlling AC current in electric circuits. This robust and cost-effective solution is a three-terminal electronic switch and can be used for two distinct purposes: switching the current flow and controlling the current levels. The TRIAC is an important device in power control applications, from the electrical level up to solid-state switching.

BCR5CM-12LB-1#BB0 Application Field and Working Principle

The BCR5CM-12LB-1#BB0 is a Thyristor TRIAC manufactured by Infineon, which is an isolatable thyristor module with an integrated diode and a controlled switching angle.

The module is designed to withstand up to 1000V turns-on surge in high-temperature environments.

The BCR5CM-12LB-1#BB0 is designed to work with a control current of 1mA, with a breakdown voltage of 800V. The module has a trigger current with a maximum value of 2.7 mA and a maximum gate trigger voltage of 2.0V. The TRIAC switching angle can be adjusted between 60 and 90 degrees for improved power performance. The BCR5CM-12LB-1#BB0 is fully insulated and provides high surge current and high operating temperature for improved power performance.

The basic operating principle of a TRIAC is to produce a controlled disturbance in AC current with the help of a gate pulse that is adjustable from 0 to 90 degrees. This gate pulse is generated by a controlling device, such as a power transistor, microcontroller or other semiconductor device. Once the gate pulse is generated, the TRIAC is opened, allowing current to flow through the device. The current can then be controlled by altering the pulse time, which increases or decreases the amount of current in the circuit. This type of control system is used in light dimmers, AC motor speed controllers and electric heaters.

The BCR5CM-12LB-1#BB0 has been designed to operate in a variety of applications, including AC motor speed controllers and lighting control systems. This robust Thyristor TRIAC is suitable for demanding industrial environments and is designed to provide reliable performance and cost-effectiveness. Its high surge current capability and wide operating temperature range help ensure that it can be used in a variety of applications.
