Hi Guys! Hope you’re well today. I welcome you on board. In this post today, I’ll detail the complete Introduction to BD138.
BD138 is a PNP transistor that is incorporated in audio amplification and switching applications. It is composed of silicon material and comes in the TO-126 package. It contains three terminals, where small input current across one terminal is used to produce large output current across the remaining two terminals. The collector-base and collector-emitter voltages are 60V with emitter-base voltage 5V that illustrates the amount of voltage it requires to bias the transistor.
