What are transistors and thyristors?

A transistor is a key component in electronics, often used as a switch or to amplify a signal from a sensor. NPN (negative-positive-negative) transistors are the most used transistor. An illustration ...

What I didn’t know about npn transistors – mosfet driving

The holiday gave me a chance to play with bipolar transistor mosfet drivers again. And things did not go quite as planned. I had been using the circuit on the right quite happily from a signal ...

Evolution of the Transistor

In the beginning, there was the point-contact transistor. This was the very first transistor ever made, built by Walter Brattain with the help of John Bardeen. It was made of two gold foil contacts ...

Key factors to consider when manufacturers are deciding between NPN and PNP transistors

Manufacturing companies, particularly those that mass-produce electronic circuits, work pretty much around bipolar junction transistors, like PNP and NPN. However, choosing between these two BJTs can ...
