The first bipolar junction transistor was invented in 1947 at Bell laboratories. “Two polarities”is abbreviated as bipolar, hence the name Bipolar junction transistor. BJT is a three terminal device ...

Transistors are the basic building blocks of integrated circuits (IC). Every electronic gadget you can possibly imagine today uses transistors. The development started off with vacuum tubes and lead ...

The HF50-150A is a 50V epitaxial silicon NPN planar transistor designed primarily for SSB communications. This device utilizes emitter ballasting to achieve extreme ruggedness under severe operating ...

What is an AND Logic Gate? The AND logic gate is a D-shaped logic gate with two inputs and one output, where the D shape in between the inputs and outputs is the logic circuit. A BJT (Bipolar Junction ...

Ever since the development of the first working transistors in 1947, the electronics industry has experienced tremendous growth in numerous ways. For instance, transistors allowed for the ...

The classic metal–oxide–semiconductor field-effect transistor (MOSFET) is the workhorse of the microelectronics industry. MOSFETs are the building blocks of microprocessors, memory chips and ...

A friend recently sent me an email noting that the classic 2N3904 bipolar transistor was now 60 years old. Since its “birth” was before I got involved with basic electronics, that callout was ...
