This video explains what transistors are and how they function as electronic switches and amplifiers. As a core component of modern electronics, transistors control the flow of current and enable ...

A Planet Analog article, “ 2N3904: Why use a 60-year-old transistor? ” by Bill Schweber, inspired some interest in this old ...

Emerging as the industry's highest voltage bipolar transistors designed for audio amplifier output stages, the MJL4281A (NPN) and MJL4302A (PNP) 15A, 230W power transistors specify a sustained ...

The first transistors were point contact devices, not far from the cats-whiskers of early radio receivers. They were fragile and expensive, and their performance was not very high. The transistor ...

Optocoupler meets automotive standards—the device squeezes 3,750-V isolation into a tiny 4-pin SO6 package. Optoisolators (also known as optocouplers or photocouplers) don’t radiate a lot of component ...

Back to analog, let us start some Schmitt trigger experiments with jellybean bipolar junction transistors… This post explores the classic emitter-coupled Schmitt Trigger circuit. A Schmitt trigger is ...
