Topic: Suggestion for a standard triac and triac driver ? (Read 372 times) previous topic - next topic

Do you people know of a standard triac able to handle at least 10 amps with a trigger current of no more than 50 mA and a suitable standard triac driver without zero crossing detection for it?

Thanks loads people. Cheers

I just built some "solid state relay" circuits using the zero-crossing MOC3043 optoisolator.
The MOC302x is a similar non-zero crossing optoisolator designed specifically to drive a TRIAC.    (The application schematic is shown on the datasheet.) 

I used this 20A* TRIAC, which has an electrically isolated mounting tab. 




* I mounted the TRIAC to an electrical box, and I'm not sure if that's enough heatsinking for 20A.  (I'm only expecting to run 2-4 Amps through it.)

random firing (non-zero) triac driver - MOC3023 (or any MOC302x)
BCR8_ - 8Arms; 30mA gate trigger
