Selection guides, application notes and design checks for rectifiers, Schottky diodes, TVS protection, MOSFETs, SiC and IGBTs — written for engineers and sourcing teams.
A catalogue tells you what exists; it does not tell you which family you need, which is the question beginners actually have. So this is a map rather than a list: each family is described by the job it does, the device it hides inside, and the mistake people make when choosing it. At the … Read more
Search this name and you will mostly get stock charts, a share price and a financial summary, because a listed company’s name doubles as a ticker lookup. That is a fair answer to a different question. This article answers the manufacturing one: why a component factory sits where it sits, what a city provides that … Read more
Search the short name and you will get a wall of datasheet archives, a distributor page and a social post before you get anything that looks like a company. That happens because the short form is what fits in a catalogue column, so it ends up attached to thousands of auto-generated pages. This article gives … Read more
Most explanations assume you already know what a discrete device is, which is why they are hard to read if you do not. This one starts from zero: what the words mean, what the company produces, where those parts end up, and how to tell whether a claim about a component is worth trusting. A … Read more
A solar garden light contains five things: a small solar panel, a diode, a rechargeable cell, a circuit that raises the cell voltage to what a light-emitting diode needs, and a light sensor that decides when to switch on. The energy is collected during the day, stored in a cell about the size of a … Read more
A modern power adapter does not simply step the mains voltage down; it chops it, transfers it across a small transformer and rebuilds it on the other side. That is why the box is small, why it works on different mains voltages, and why it can hold a steady 5 V while the socket voltage … Read more
An LED bulb makes light by passing current through a semiconductor junction, which converts some of the electrical energy directly into photons instead of heating a filament until it glows. That is the reason it uses far less power for the same light and why it runs cooler than the bulb it replaced. But the … Read more
A desktop power supply converts the alternating current from the wall socket into three steady direct voltages that the computer uses: 12 V for the processor and graphics card, 5 V and 3.3 V for the rest. It does that with the same five stages as any switching converter — rectification, switching, a transformer, output … Read more
Inside a power bank there are four blocks: cells that store energy, a converter that changes the cell voltage into the voltage your device expects, protection circuitry that keeps the cells inside their safe operating range, and the connectors and indicator that connect all of it to the outside world. The gap between the number … Read more
Reliability engineers ask rectifier questions with two words that sound similar and mean different things: thermal cycling and power cycling. Both wear a part out, both are drawn as life curves, and both are explained by one number — the delta-T of the cycle. But they attack different parts of the package, predict different lives, … Read more
Thermal design for a rectifier is the one part of power design that engineers often treat as a black box, yet it reduces to a single equation and a clear chain of thermal resistances. Get that equation right and the same method sizes an axial diode, a TO-220 rectifier, and an SMD part; miss it … Read more
The 12 V automotive rail is the one power bus nearly every electronic module on a car shares, and it is also the least “regulated” rail an engineer will ever design against. Over a single day of driving, the same two terminals that start the engine with a few hundred amps also carry the alternator’s … Read more
