TVS Diodes
TVS diodes protect circuits from voltage spikes. Let's discover what they are and what makes them special!
Zener Diodes as Shunt Regulator
Building a voltage source for small circuits with a zener diode? Let's explore how this is possible, let's build a shunt regulator.
Zener Diode Low Voltage Alarm
Today, we are going to build a low voltage alarm using a zener diode and an LM393 comparator.
Zener Diodes as Voltage Reference
What can we use zener diodes for? This time, we look at their use as voltage references.
Avalanche Breakdown
Let's learn more about the second important breakdown effect in zener diodes: the avalanche breakdown.
Zener Effect
The zener effect is the dominant breakdown effect in low voltage zener diodes. Let's take some time to learn more about it.
Zener Diodes
It is a special type of diode designed to operate reverse biased: the zener diode.
Flyback Diodes
It is a necessary component in many circuits with inductive loads: the flyback diode.
Full-Wave Bridge Rectifier
It is used in many products and is de facto the standard rectifier: the full-wave bridge rectifier. Let's discover how it works.
Half-Wave Rectifier
A popular application for diodes are rectifier circuits. Today, we are going to look at a simple half-wave rectifier.
Alternating Current
Before we look at rectifier circuits, let's take a brief look at alternating current.
Reverse Polarity Protection
A reverse voltage can easily damage electronic circuits. Let's look at simple reverse polarity protection circuits using diodes.
A diode is like a one-way road for electric current. Let's have a look at this simple semiconductor components.
P-N Junction
Let's look at the foundation for transistors, diodes and many other semiconductor components: the p-n junction.
Light Dependent Resistors
Light dependent resistors are an easy solution for reacting to brightness changes. Let's discover their properties!
A world without semiconductor components has become unthinkable. But what are they and what makes them that special?
Temperature Measurement with NTCs
NTCs are often used as temperature sensors. To use them, we need to know how to calculate a temperature value out of the measured resistance.
The resistivity of materials is dependent on temperature. Thermistors are electric components which make use of this.
Resistance Measurement
We talked a lot about voltage dividers and resistance, but how can we actually measure resistance?
