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.

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 for such a …

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 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-crossing opto …

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, 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

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 …

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.

Jan 18, 2022 · Hello, I made this circuit so I can control a 24VAC sprinkler solenoid valve (rain bird ones from home depot), using a microcontroller. I also want to mention that I am new to using triacs by the …
