How would you test a sensitive gate TRIAC?

[Dave]

Trying to fix something for a family member, and suspect the NTE56041 TRIAC
is faulty. Only I have no idea as to how to test this device. Anyone have
any ideas? TIA for any help...

I use a stand alone lamp dimmer with the triac removed and extended to a
test socket

Replace it, they're cheep, 2 bucks. If it's an NTE marked part # it's
been replaced before.

Aaahh. Thank you. That is something I can shoot for. Was thinking I
needed to build some kind of test jig, but that is a better idea. Many
thanks,

Dave

Yeah, I just wanted to know how to test it, to maybe save a trip across
town by bus. If my candy store stocks this part, I may just do that though.

Thanks,

Dave

Placing the device in a known working circuit is the only real way to
test it.

Dave-

Since it appears to have been replaced before, you should think about
what made it fail.

Using the same TRIAC could lead to another failure. It is possible that
the NTE56041 is not a correct replacement for the original failed TRIAC.
Unfortunately you may not have the original part, so you can't double
check the cross reference.

You might examine the application to determine maximum voltage and
current, and verify the NTE part should work. See
<http://www.nteinc.com/> for specs.
