Hello Ivica.
circle on transistor symbol is used to indicate that this is discrete
component (individually packaged transistor - has nothing to do with
form or shape of package). transistors without circle therefore
indicate that they are part of IC circuit (look at schematics of opamp
or gates for example).
Nice to know and would make sense. Can you give me a point to the
official source of this statement? I want to discuss it with the local
EN-standard supplier here, because the lack of this information in his
papers.
So here you find this fat single (mostly MOSFET) Transistors normally
without circle in the schematics.
