What is triac used for?

Triacs are electronic components that are widely used in AC power control applications. They are able to switch high voltages and high levels of current, and over both parts of an AC waveform. This makes triac circuits ideal for use in a variety of applications where power switching is needed.

Is a triac AC or DC?

A triac switch is a semiconductor device used in an AC voltage circuit that expands upon a typical thyristor device. Triac switches excel at directly controlling relays and/or starter coils in motors used in AC circuits. Transistor switches, on the other hand, operate with a DC voltage circuit.

Can a triac be used for DC?

So it has very limited applications on the dc field. Ultimately, The TRIAC is a three-terminal electronic device, which works as a switch for AC signals. With a small current injected on the GATE(can also be a DC source), it enables a relatively high AC current between T1 and T2 terminals.

What is triac operation?

A triac is a five layer, three terminal semiconductor device. Until the voltage across the triac is less than the reverse breakover voltage, device operates in a reverse blocking mode. A traic can be made conductive by either positive or negative voltage at the gate terminal.

What are the advantages of 600V 6h TRIACs?

Our 600 V 6H triacs are high-temperature triacs with an easy, low-current gate drive. They offer high switching rates and the sparkless features of semiconductors, a significant advantage over traditional relay devices. Phase angle drive of the gate allows simple dimming for lighting and variable speeds for universal motors.

What’s the maximum current of a St TRIAC?

Featuring a maximum current of 50 A with standard or logic-level gate sensitivity, ST offers two different series: 600 V 6H triacs and 800 V 8H triacs. Both are available in D²PAK, I²PAK or TO-220 (I) packages.
