Now return to our inductive circuit. The solid-state triac device ensures that the circuit’s energy flow is interrupted only when the ac current waveform reaches its instantaneous zero.

A triac is used in a discrete phase-control circuit to control the speed of a vacuum-cleaner motor. Confirm by calculating for worst-case conditions that the triac's T JMAX of 125°C will not be ...

Designing an AC circuit for controlling LED light output is very simple when using the newest triac designs, such as the Littelfuse Q6008LH1LED or Q6012LH1LED Series, because the only components ...

In electrical heating applications, resistive heaters are powered through phase angle-controlled SCR/triac circuits to vary the applied voltage/power to maintain the required temperature. Phase angle ...

These devices are all triggered thanks to a gate current, but this current could be sunk from or sourced to the gate, depending on the technology or design. The triggering circuit has then to take ...
