Triac bt 137 and 138
You have to clarify if it is a BLD138D, because it does not appear to me as a triac.
A BT 137 of 7A, you can replace it with a BT138 of 12A. For the same or greater tension. But not vice versa.
You did not understand me. The BLD139D is a transistor, not a triac.

I can think of a BTA12 or a BTB12 I need the biggest one because it is for a machine with a graphic that has a motor and 2 resistances greetings
We cannot know if the BT138 is well sized without knowing the power of the motor and of the resistors.
Ready colleague, I solved it, thanks to me, I put a BTB16 600V well coped and walked, cordial greetings
The BT139 is 16A.
There are more current triac such as the BTA26-600B, which is 25A 600V.
