Types of TRIAC
Generally there are some types of TRIAC as follows:
- General useful TRIACs: These are flexible TRIACs intended for many range applications. They are regularly utilized in light dimmers, motor speed controls, and other universally useful AC power control circuits.
- Sensitive Gate TRIACs: Sensitive Gate TRIACs require lower triggering current and are profoundly receptive to control signals. They are reasonable for applications where low-power control signals are accessible.
- High Commutation TRIACs: High compensation TRIACs are intended to deal with high paces of progress of current (di/dt). They are in many cases utilized in applications where quick exchanging happens to limit the gamble of false triggering.
- High-temperature TRIACs: These TRIACs are intended to work proficiently at raised temperatures. They find applications in conditions where heat dispersal is a basic variable.
- Low Holding Current TRIACs: Low holding current TRIACs require a lower current to keep up with conduction once triggered. This element can be helpful in applications where it is critical to limit power utilization.
- Gate Trigger Current Variations: TRIACs are accessible with various door trigger current details. Standard TRIACs have a commonplace door trigger current, while high and low trigger current variations take care of explicit application prerequisites.
- Snubberless TRIACs: Snubberless TRIACs consolidate an implicit snubber organization to ingest the energy created during exchanging changes. This diminishes the requirement for outside snubber circuits and improves on plan in specific applications.
TRIAC
We know that a unidirectional device like a SCR incorporates the characteristics of the reverse blocking current since it stops the progression of current in a reverse-biased state however for a few applications, this sort of current control is essential, particularly in AC circuits. So this can be accomplished through SCRs, where the association of two SCRs ought to be finished in enemy of lined up for controlling over both positive as well as bad information half cycles. However, this game plan can be changed through a unique semiconductor device called TRIAC, used to accomplish bidirectional control. This device controls the air conditioner unequivocally and every now and again utilized in controlling the speed of the engine, AC control devices, AC circuits, light dimmers, pressure control systems, and so on.
