The circuit is from old documentation but can be implemented with any modern power MOSFET. The type of MOSFET depends only on the voltage and current of the controlled load.
The circuit shown is from an old European publication. In it we have the way to activate a relay...
We found this circuit in a European publication from the 1990s. Transistors are still common types...
This circuit was found in an American documentation and can be added to common amplifiers of any...
