- Half_burned triac - All About Circuits
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, one of triacs that has a parallel RC equivalent load is half-burned (triac is short-circuited in one direction)
- Triac light dimmer controlled with DC voltage - All About Circuits
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 circuit, I either find: 1) The basic light dimmer using a triac with a diac and a variable resistor
- Triac burn out - All About Circuits
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 not overheating

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:
- TRIAC ANALYSIS-Calculation of gate resistor - All About Circuits
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

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

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 for open circuit
- Soft start using triac - All About Circuits
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 resistance R3 as a variable value determined by the voltage source The system to perform a soft start for the
