How many gates does a triac has

Web5 mei 2024 · Mosfet is a voltage-driven device and Triac is a current driven device. Triac is self-sustaining and Mosfet is (practically) not self-sustaining. Once you have turned on a triac (it starts to conduct), it will remain conducting all by itself until the current reverses. Mosfets, because of its leakage, will turn off over time. Web30 okt. 2024 · It’s true that a trailing edge dimmer with 400W of capacity can easily handle 400W of incandescent bulbs, but the most LEDs can handle is just 10W. That is to say, our 400W dimmer can only control a maximum of 40W of LED lights. Low-wattage loads are most effectively managed by trailing-edge dimmers.
