From small LED drivers to rectifiers to Switch Mode Power Supplies (SMPS), the diode is a key component in each of those everyday appliances. They are also used in charging LED indicators and reverse polarity protection circuits in router chargers and many more; diodes are used...

David Jones made a tutorial on the fundamentals of zener diodes over his EEVblog youtube channel. David started the tutorial comparing between zener and regular diode. Both have the same characteristics and same I-V chart, but zener is designed to work in the negative voltage...

Let's have a look at what Zener Diodes are, and how they work! What is a Zener Diode? -...

Tiny low current 9 VDC Regulated Power supply designed around bipolar transistor and zener diode. The circuit is known as series voltage regulator or emitter follower voltage regulator. The unregulated supply fed to input and the circuit regulate the voltage and provide constant 9V...

by Lyle Russell Williams: You can use three discrete transistors to build an operational amplifier with an open-loop gain greater than 1 million (Figure 1). You bias the output at approximately one-half the supply voltage using the combined voltage drops across zener diode D1, the...
