Semiconductor devices are at the heart of every modern electronic and industrial system. From basic power rectification to advanced motor drives and welding equipment, their role is fundamental. Yet many engineers, technicians, and decision-makers still ask the same question: What's the difference between a diode, a transistor, and a thyristor (SCR)?
To make this easier, we've prepared a three-part guide that walks you through these essential devices step by step — from fundamentals to real-world industrial applications. Depending on your background and needs, you can dive directly into the part that matters most to you.
If you're starting with the basics or working in power supply design, this article is for you.
We explain how diodes allow current to flow in one direction, their critical role in rectification, and their limitations when it comes to controlling power. A perfect entry point for anyone curious about the building blocks of electronics.
