B772 comes with three layers where two are p-doped layers and one is n-doped.This PNP transistor is made up of silicon material and comes in the TO-126 package.During the amplification process in the circuit, the small input current present at the base terminal is used to produce large output current at the remaining terminals. ![]() It contains three pins called the emitter, collector, and base terminals.B772 is a bipolar junction transistor that falls under the category of PNP transistors.In this post, I’ll be discussing pinout, datasheet, working principle, power ratings, physical dimensions, and applications of B772. The 60V is the collector-base voltage and 30V is the collector-emitter voltage while 5V is the emitter-base voltage which means it requires 5V to bias the transistor and start transistor action. It comes in the TO-126 package and carries a collector current of 3A which means it can support load under 3A. In this post today, I’ll walk you through the Introduction to B772.ī772 is a medium power bipolar junction transistor mainly used for switching and amplification purpose and belongs to the PNP transistor family. ![]()
