Transistor Schéma !!link!! Page

Sur un schéma, le symbole graphique indique non seulement le type de composant, mais aussi le sens de circulation du courant. On distingue deux grandes familles : Transistors - SparkFun Learn Transistors - SparkFun Learn NPN VS PNP Transistor Symbols

The arrow in the symbol always points from the P-type material to the N-type material, indicating the direction of conventional current flow (e.g., pointing out of the emitter in an NPN transistor). transistor schéma
