The figure shows a circuit that shows how to control an optodiac to trigger a triac from the LM3914 gates. The circuit is from an Electronics Now issue from February 1998.
In the figure we have a typical polarization circuit for MOSFETs with a high impedance...
Equivalent transistors, like the BC548 and BC558 pair can be used in this circuit that we find in an...
The circuit presented is from an old magazine having been translated and published in a national...
