In this article, we’re going to focus on using common bipolar junction transistors instead of relays ... more than sufficient in this case. Most NPN-type BJTs will work fine though.

If you want to control it from a 3.3 V MCU that can’t handle the high-side voltage on its pins, you can add a NPN transistor section ... in P-FET datasheets, Vgs is shown as a negative number ...

The transistor is considered to be one of the most important inventions of the 20 th century because of its abundant use in most modern circuits and electronic systems. NPN and PNP are the two ...

and Field Effect Transistors (FETs). BJTs are controlled by current, while FETs are controlled by voltage. Within these categories, there are further subdivisions such as NPN and PNP BJTs and ...

Supplemental information from current and past issues of the Journal of Accounting Research. Users downloading any of the files provided as part of our data and code sharing policy certify that they ...

But in 1951, Shockley improved upon the original idea with a junction transistor. The importance of this small item gradually sank in. The transistor was a solid (thus the term "solid-state ...

The electronic transistor and the logic gates based on it have qualitative features that are crucial for systems of any complexity, but very few optical transistors or logic devices possess them 3.

If transistors could replace vacuum tubes in the phone system, then they certainly could replace them in computers too. The army, with its need for ever-faster and more efficient calculations ...

Transistors are easily damaged so it is important not to mix up the three legs. To help identify the legs, some transistors have a dot near the collector, and/or a tab near the emitter.

There are several basic types of RF transistors: Bipolar RF transistors: Consist of an N-type or P-type layer sandwiched between two layers of the opposite type. Both NPN and PNP configurations are ...
