How to Use TVS Diode to Suppress Transient Voltage

Diode is the most basic semiconductor device, usually used in many electronic design, such as rectifier, converter, inverter, protection circuit, regulator, etc. The three most common types of diodes are rectifier diodes (general purpose diodes), zener diodes and Schottky diodes. We have learned the basic knowledge and working principle of diodes. But there is another special diode called TVS diode, which plays an important role in dealing with the transient spikes in power electronic design circuits. In this paper, we will study the transient voltage suppressor and why it is needed in the circuit.

Digital to Analog Converter Introduction

When talking about signals, they can be roughly divided into analog signals and digital signals. All digital electronic devices (such as logic gates, triggers, microcontrollers, microprocessors, etc.) can process digital signals, while analog electronic devices (such as operational amplifiers, power switches, etc.) can work. In a typical electronic design, these two signals usually have to be converted from one form to another. We’ve learned how to use an analog-to-digital converter (ADC) to convert analog signals to digital values. In this article, we will learn how to use DAC to convert digital signals to analog voltages.
