- 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)

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
- 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
- Driving transformer primary side with TRIAC - All About Circuits
Use burst mode, but turn on the Triac on the Voltage peak Turn it off on zero current (the natural commutation point of a triac ) This avoids (a) large inrush currents (b) large voltage spikes from energy stored in core inductance 1 Magnetizing Current (Im) The magnetizing current is the small current that flows in the primary winding even when the secondary is open (no load) It is required
- Switching a 24VAC solenoid, TRIAC, Relay or SSR?
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

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:
- Unable to run the a Triac simulation in LtSpice.
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 triac", I haven't been able to figure out how to get past this or found a simulation online Anyone can help?
- Motor control using MOC3041 optocoupler | All About Circuits
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-triacs will generally manage without
