Thyristors are a type of semiconductor device that switches power for controlling current or voltage in an electronic circuit. TRIACs (alternating current gate-turn-off thyristors) are a type of thyristor that can alternately connect or disconnect either side of an AC circuit to the other side like a switch. The Q2010RH5 is a type of TRIAC that has a wide range of applications. This article will explain its application field and working principle.

Q2010RH5 application field

The Q2010RH5 is an ultra fast and bidirectional TRIAC with a maximum peak blocking voltage of 200V. It is available in a TO-92 package and is capable of handling a continuous RMS on-state current of 2A. Due to its bidirectional nature, it can be used to control current in both directions. This makes it an ideal choice for controlling power from AC sources such as home appliances, lighting, air conditioners, and other electrical equipment. It is also commonly used in motor drives, inertial guidance systems, heating and cooling systems, power supplies, motor controllers, alarm systems and pulse generators.

Q2010RH5 working principle

The Q2010RH5 is basically a two terminals device, the gate and the main terminals (MT1 and MT2). When a signal is applied to the gate, the device is triggered and turns on the flow of current from MT1 to MT2. The gate current is used to control the output current of the TRIAC. The flow of current through the TRIAC is controlled by the voltage across it, which is determined by the resistance of the load. When the resistance of the load changes, the gate current needs to change accordingly to maintain the desired output current. The output current can be adjusted by varying the gate current or the applied voltage.

Conclusion

The Q2010RH5 is a bidirectional TRIAC with a 2A continuous RMS on-state current rating. It is highly flexible and can be used in a wide range of applications from home appliances to motor drives. Its working principle involves triggering the device with a signal applied to its gate, which controls the output current of the TRIAC.
