NPN and PNP are both known to be transistors, but they have some differences with each other. NPN transistor usually turns on when the current will flow from the base of the transistor. This means that the flow will come from the collector going to the emitter. The PNP transistor, on the other hand, will turn on when there is no current that comes from the base of the transistor.

The NPN will use electrons as charge carriers while the PNP will use holes as the charge carriers. It will still depend on people who will be more ideal for their needs. Most people would prefer electrons, though as compared to holes, which means that NPN may be more suitable for a lot of users.

NPN and PNP are transistors. Specifically, they are both bipolar junction transistors. They can be classified as 3-terminal electronic semiconductor devices. If someone wants to switch transistors or amplify them, they will use either an NPN or PNP.

If you wish to a transistor that had lower electron mobility, then you should use PNP because NPN had more electron mobility. That is why people prefer NPN transistors to PNP. Manufacturers can produce NPN with more ease than PNP because it is created from silicon. The base is the main difference between the NPN and PNP. For the bottom of the NPN, you would see a P-dope semiconductor. The support for the PNP is called the N-dope semiconductor. Now that you know the difference, you can select the one that works best for you.
