They switch on with a base voltage of around 0.6V to 0.8V. Circuit diagrams often show transistors in switching circuits. For an ideal NPN transistor, the switch-on voltage at the base is ...

This circuit is called a high-side switch – it enables you to toggle ... enough that we typically just refer to them as NPN or PNP transistors. These are all under the transistor umbrella ...

In this article, we’re going to focus on using common bipolar junction transistors instead ... A simple test circuit (using a switch to provide the current needed instead of a microcontroller ...

They can amplify or switch signals with low power consumption, easily adapt to various circuit configurations ... types of semiconductor material. What does "NPN" or "PNP" mean in terms of a ...
