Hello everybody and thanks in advance. Well, as I say in the title, how can I check this component, It is from an air conditioning card, and it literally explodes due to a voltage surge, (the components of the rest of the card look good, except for the blown fuse, which already changes, the varistor already checks and is fine, etc. ). I have another TSA 3100j just like a discarded card and I would like to check that it is ok before changing it. Greetings

Hi. This is the component you mention? In its description is the circuit inside. Between its legs 4 and 5 you should try it as a diode and in the remaining three as a triac. Regards https://pdf1.alldatasheet.es/datasheet-pdf/view/32544/TOSHIBA/TSA3100J.html

Thank you very much for the answer,
I had already seen the datasheet,
between legs 4 and 5 I had already tried them as a diode and that's fine,
among the others he had tried them as a triac,
it gives me resistance between gate and leg 2, both ways,
leg 1 with 2 and with the door nothing at all in both directions.
is that bad then?
I, from my ignorance, understand that the component works like two triac.
In a triac, the gate is a LED that activates the gate and that gives way to the gate of the other triac.
Is that so or am I wrong?

observation, on the card that is mounted, pin 3 is soldered but the track does not go anywhere
