Nov 2, 2024 · Hi, In a dishwasher machine main board we have used 107NN0 triac for controlling ac loads such as valves, pumps, dispenser, etc. In about 2 to 3 percent of products sold to …

Oct 20, 2025 · The current waveform shows your triac triggering half wave. That is because the gate resistor is far too small, and there isn't enough voltage across it to generate sufficient …

Dec 5, 2022 · Hi everyone, I want to develop a soft start system for the receiver. In real system, it is a power supply in the laboratory with a variable resistance value - hence programming the …

Dec 8, 2017 · I have searched online in attempt to see how I can setup my spice model to run a simulation on a triac. But I keep getting this error: "Unknown subcircuit called in: xu1 n003 …

Apr 20, 2021 · Hi, I'm doing a small project, in which I control a regular home fan from my processor. I use a triac (BTA12-600BW3G) to shift the phase of the current and this way I can …

Jul 26, 2022 · Triac failures are usually caused by either excess current or excess voltage, either to the gate or through the device, and if they happen at the moment of turn on application it is …

Oct 20, 2016 · The Triac needs a maximum of 10mA gate current, the supply is 230V, so with R1at 10K, R2+3 needs to drop 130V, which gives 13K total at 1.5W.. simple ohms law

Nov 8, 2020 · anybody know where I can get a good triac model for use in ltspice simulation? been looking like forever. got a diac model that works.

Jan 6, 2018 · These use a triac control readily, sometimes a bridge is added. All you need to do to confirm it is to lift or otherwise insulate one brush and measure the motor terminal resistance …

Jun 27, 2017 · Triac's do not have this problem because theoretically the current must be zero when they turn off. You can trick a triac with a transistor, but then you're back to the transistor …
