Thyristors - TRIACs

A TRIAC, short for TRIode for Alternating Current, is a three-terminal semiconductor device. It is an electronic component that is able to control AC current in a bidirectional fashion. TRIACs are part of a group of related components known as thyristors and are commonly used as electronic switches. The TIC226D-S is a TRIAC component that belongs to this family.

Application Field of TIC226D-S

The TIC226D-S are typically used as AC switches in a variety of applications. These includes motor control, light dimmer applications, temperature control and other general purpose AC switching applications. The device is suitable for applications where low power dissipation is required and has enclosed sensitive gate which helps provides a sensitive operation. The TIC226D-S is extensively used in a variety of applications due to its ability to control the voltage applied to a load from a low to a high level. Additionally, its small size and low cost makes it an desirable choice for many applications.

Working Principle of TIC226D-S

The TIC226D-S TRIAC consists of two thyristors that are connected back-to-back. This configuration allows it to switch the current in both directions, from a low to a high level and from a high to a low level. When the gate current is applied, the device assigns a voltage to a load, allowing the current to flow and establishing an AC signal. The TRIAC remains active while the TIC226D-S is in the on state, allowing the current to flow and the voltage applied to the load to be adjusted.

Once the TRIAC is in the on state, it is not affected by reversals in current. However, the control gate must be connected to a positive voltage relative to the negative voltage applied to the TRIAC in order to make it remain in the on state. The TIC226D-S has an operating temperature range of -40°C to 125°C and a reverse breakdown voltage of 20V. It is made from environmentally friendly materials and is thus RoHS compliant.

Conclusion

The TIC226D-S is a versatile and cost-effective TRIAC component that is suitable for a wide range of applications including motor control, temperature control, light dimmer and general purpose AC switching. The TRIAC works by switching current from a low to a high level and vice versa and utilizes an enclosed sensitive gate for control purposes. The device is also RoHS compliant and has an operational temperature range of -40°C to 125°C.
