This power transistor comprises a plurality of elementary transistors, also indicated as 'fingers', having their emitter terminals mutually connected and forming a common emitter terminal, collector terminals also mutually connected and forming a common collector terminal, and base terminals connected to at least one current source. Each elementary transistor is part of a circuit comprising a diode forming, together with the elementary transistor, a current mirror, so that the collector current passing through the elementary transistor is far less sensitive to the temperature gradients which originate inside the power transistor.
