Reply to "Mini Commander triacs"

Professor ChaosOGR Forum Member

Thanks John - I was thinking of the Mini Commander HC/ACC, not the MC2. How easy is it to implement variable control of AC with MOSFETs? Is it the same notion of duty cycle as it is for a triac?

I poked and prodded one of my Mini Commander HCs and was able to pick out the HC triacs as T2322BG. This raises two questions:

1) The older Mini Commander HC had one T2322B and one beefier triac in a TO-222-2 package for the higher current output. What was the change that permitted use of the smaller T2322B for the same applications?

2) Is the T322B still a good choice for this kind of application, if we're sticking with triacs? The 2N607 series seems to have a lower on-state voltage and holding current, but I'm not familiar enough with triacs to know if those are good things.
