A diode is a device that allows current to flow in one direction but not in the other. This ability makes diodes useful in many applications, including converting AC to DC, regulating voltages, and ...

The history of the diode is a fun one as it’s rife with accidental discoveries, sometimes having to wait decades for a use for what was found. Two examples of that are our first two topics: thermionic ...

When we use an electronic component, we have some idea of what goes on inside it. We know that inside a transistor there’s a little piece of semiconductor with a junction made from differently doped ...

Comparison of a 5W laser, 10W, and 20W diode laser. All these machines have their pros and their cons, but this is a quick ...

Where there is power there is heat, and where there is heat there is often a need to sense temperature (the most widely sensed physical variable). What we call temperature is our measurement of a ...
