triac help
Hey,
I am trying to put together an ac switch using a triac and a MOC3020. I've tried simulating it with the circuit given in the MOC302x datasheet, but the triac seems to latch and not want to "unlatch". (for sim purposes I used Q4015L5 triac...couldn't find IT415 lib)
I can reduce the gate current so it doesnt' latch and it works fine when I take away the gate it stops conducting...the problem is I don't want to supply the gate current the whole time since I'd be wasting massive amounts of power compared to the latching technique.
Anyways, I was wondering if anyone had any experience with triacs and could tell me a little by about this latching thing. I've found pdf's on it, but they only concern having the right amount of gate current and pulse width to make it latch, not unlatch. Thanks in advance.
edit:
Er don't mind the diode before the MOC, I was trying to trigger it directly before and forgot to take it out
