Thyristors - TRIACs

A TRIAC is a single bidirectional switch that not only provides the signal amplification and signal routing capabilities of a traditional transistor, but is also capable of connecting two different signal sources together. TRIACs are often referred to as “electronic switches” because they can be used to control voltage and current in both directions. A TRIAC is ideal for electronic switching applications such as relays, motor/light controls, speed control systems, TV/VCR systems and other consumer electronics.

The BCR5FM-14LJ#BB0 is a highly reliable and efficient bidirectional thyristor (also known as TRIAC), designed specifically for a wide range of applications. It has a wide operating voltage range of 5-14 Volts and can control current up to 0.1 Amps. The TRIAC is highly efficient, with a low on-state voltage drop and low on-state resistance, and low switching energy loss. It features low power dissipation, minimal thermal behaviour, and fast switching speeds.

Application Field:

The BCR5FM-14LJ#BB0 is a general purpose TRIAC device that is suitable for a wide range of electronic switching applications, including relays, motor/light control, speed control systems, TV/VCR systems, consumer electronics, and other industrial applications. It is ideal for synchronous motors and inductive loads, as well as high-speed switching applications. The low on-state resistance of this device makes it particularly suitable for applications that require high switching speed and low power losses.

Working Principle:

The BCR5FM-14LJ#BB0 is a bidirectional thyristor (also known as a TRIAC), meaning it can control current in two directions. The device consists of two MOSFETs connected back-to-back with a common gate, which is analogous to the diode bridge circuit. When the gate voltage reaches its threshold, the TRIAC conducts current in both directions until the gate voltage is removed or decreased. The device can be paralleled with other TRIACs for higher current capacity, but it is important to note that the devices must be of the same type and voltage rating for the parallel connection to be reliable.

The TRIAC can be triggered using either an AC or a DC voltage source. When using a DC voltage source, the gate circuit needs to be designed in a way that prevents the gate voltage from entering the main circuit. When using an AC voltage source, the gate voltage is supplied through the main terminals and the TRIAC can be triggered without additional circuits. In addition, the maximum gate voltage must be limited to ensure proper operation of the device.

The BCR5FM-14LJ#BB0 has a wide operating voltage range of 5-14 Volts and can handle up to 0.1 Amps of current in both directions. It is also designed for long-term reliability and low power dissipation, with a low on-state voltage drop and low on-state resistance. It also features fast switching speeds and minimal thermal behaviour, making it ideal for high-speed switching applications.

Conclusion:

The BCR5FM-14LJ#BB0 is a general purpose TRIAC device that is suitable for a wide range of electronic switching applications. It has a wide operating voltage range of 5-14 Volts and can control current up to 0.1 Amps. The device features low power dissipation, minimal thermal behaviour and fast switching speeds, making it ideal for high-speed switching applications. It is designed for long-term reliability and low power dissipation, with a low on-state voltage drop and low on-state resistance. The BCR5FM-14LJ#BB0 is the perfect choice for high-speed switching applications that require reliability and efficiency.
