  1. Driving transformer primary side with TRIAC - All About Circuits

    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 …

  2. Half_burned triac - All About Circuits

    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 …

  3. Triac light dimmer controlled with DC voltage - All About Circuits

    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 …

  4. Triac burn out - All About Circuits

    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 …

  5. Supress Energy coming from Inductive load when controlled using …

    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 …

  6. triac model for ltspice - All About Circuits

    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.

  7. Triac Identification - All About Circuits

    May 26, 2024 · The triac that's connected to the heater T2 (terminals A1 & G), on the diode setting of the multimeter, reads .072, and the other triac T1 reads .037. The triac numbers are:

  8. Triac, M1/M2 always interchangeable, or sometimes or what?

    Jun 9, 2020 · Hello, When a triac or thyristor is fired, it needs the voltage to go to almost zero to reset. The triac or thyristor will "reset" below the holding current. Bertus

  9. Using A Triac OptoIsolator for DC-DC Switching - All About Circuits

    Sep 21, 2019 · The triac doesn't care whether it is switching AC or DC. Assuming that all other specs are okay for your application, then yes, you can certainly switch a DC voltage on/off.

  10. Unable to run the a Triac simulation in LtSpice.

    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 …
