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 power loss.

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 heating …

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 spike problem.

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.

Mar 8, 2012 · Hello all! I am still a bit novice about electronics so i thought if someone could give some comments about this. I want to control a resistive heating element according to it's temperature. I …

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 most likely …

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 customers, …

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:

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

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 n004 0 …
