PNP and NPN transistors are crucial components in industrial wiring since they control the current flow in circuits. By understanding these two types of transistors well and knowing when and how to convert their output signals, you can significantly benefit from using them. This article will walk you through the most common applications of PNP to NPN converter circuits, explain why you need to use them and provide a guide on how to use them effectively.
What Are PNP and NPN Transistors?
When it comes to any circuit that needs a bipolar junction transistor (BJT), PNP and NPN (respectively "positive-negative-positive" and "negative-positive-negative") transistors are the primary choices. The difference between these two is in the type of charge carriers and the direction of the current flow. Both transistors are activated by a small current being applied to the base. However, in the case of that current being applied, the current flows from the emitter to the collector in a PNP transistor,
