Oct 20, 2025 · It's a high-commutation triac, so it doesn't necessarily need a snubber, but adding a snubber never did any harm. And, just out of interest, what is the voltage and current of the …

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 …

Aug 4, 2023 · I am looking for a way to make a "light dimmer" (actually controlling a heating coil) using a triac, where I can control the duty cycle of the AC based on a DC voltage. In searching …

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.

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 …

Nov 1, 2020 · A triac or SSR will drop about 1Volt, so will dissipate 1 Watt for each amp of current so you should check heat dissipation. Switching a DC solenoid with a MOSFET will incur less …

Aug 29, 2023 · The above waveform attached shows input sinewave which is stepped down using transformer and I am using voltage based zero cross detection for firing Triac. Above …

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 …

May 1, 2022 · The BW type triac is marketed as "snubberless" because it will withstand a high dV/dt. The opto-triac isn't quite as good with dV/dt so best to keep the snubber, but zero …

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 …
