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.

What does "NPN" or "PNP" mean in terms of a transistor? "NPN" and "PNP" refer to the arrangement of the different types of semiconductor material in a Bipolar Junction Transistor (BJT). In an NPN ...

Radiation effects on bipolar junction transistors (BJTs ... formed at the SiO2/Si interface in gate-controlled lateral PNP transistors. It found that ionizing radiation creates two types of ...

The PN junction is one of the primary building ... These p-type/n-type bipolar "sandwiches" are called "PNP" and "NPN" transistors. See bipolar transistor and n-type silicon.

Also called a "bipolar junction transistor" (BJT), it is one of two major transistor categories; the other is "field-effect transistor" (FET). Although the first transistor was bipolar and the ...

This course presents in-depth discussion and analysis of metal-oxide-semiconductor field-effect transistors (MOSFETs) and bipolar junction transistors (BJTs) including the equilibrium characteristics, ...
