Thyristors - TRIACs

Thyristors, commonly referred to as TRIACs, are a type of electronic device used in power control applications. A TRIAC is a three terminal device, usually containing a positive and a negative terminal, and a control terminal. They are used to control the power, voltage and current supplied to a load. The 2N6071BG is one such device and is used for applications such as AC switching and thyristor power control.

Application Field of 2N6071BG

2N6071BG is a high-performance 3 A 100 V, 4 A 200 V TRIAC with a zero gate trigger current, low thermal resistance and high dV/dt capability. It is mainly used for general purpose AC switching and thyristor power control. This device is suitable for usage in communication systems, sound systems, electro-acoustic systems, monitoring systems, smart home systems and industrial automation systems. It is also used for applications like triac dimmer, light dimmer, AC motor control and heater control. The maximum junction temperature of the 2N6071BG is 150°C.

Working Principle of 2N6071BG

A TRIAC is a three terminal device, usually containing a positive and a negative terminal, and a control terminal. When a current is applied to the control terminal, it triggers the TRIAC into conduction and current flows through the two main terminals. The 2N6071BG is a TRIAC that uses a zero gate trigger current and requires very low gate current to trigger on. This device is triggered with two different gate voltages; a negative voltage to trigger off and a positive voltage to trigger on.

The 2N6071BG has two modes of operation: load or no load. During no load operation, the gate current is set to the minimum off level and the TRIAC will be on until the current flowing through the TRIAC is below its minimum off level. During load operation, the gate current is set to the maximum on level and the TRIAC will be on until the current flowing through the TRIAC is above its maximum off level.

The 2N6071BG also has an input threshold voltage, which is the minimum positive gate signal voltage level required to trigger on the TRIAC. When this voltage is exceeded, the TRIAC will be on. This feature increases the safe operating area of the device and prevents the TRIAC from being damaged due to abnormal currents. In addition, the 2N6071BG is protected against reverse voltage which helps prevent premature failure.

Conclusion

The 2N6071BG is a three-terminal device used mainly for general purpose AC switching and thyristor power control. It has a zero gate trigger current and offers protection against reverse voltage. The maximum junction temperature of the device is 150°C. The 2N6071BG is a high-performance TRIAC and is suitable for use in many systems such as communication systems, sound systems, electro-acoustic systems and industrial automation systems.
