Characteristics of Power Semiconductor Components
In addition to IGBT, representative products in power semiconductor components (transistor field) include MOSFET, BIPOLAR, etc., which are mainly used as semiconductor switches. According to their respective supported switching speeds, BIPOLAR is suitable for...

      The impact of lightning strikes and surges is an often overlooked important risk factor. Lack of preventive measures can lead to serious consequences, such as fires, important equipment shutdowns, and misoperations. Therefore, lightning and surge protection measures are an important component of safety schemes, because modern society is a large whole working together and cooperating.

      Lightning and surge protection should be considered in the early stages of project planning, as implementation is much easier in the early stages. Later modifications will be difficult to achieve...

ISO指International organization for Standardization（国际标准化组织），是总部设在瑞士日内瓦的非政府机构。制定了许多国际标准（IS：International Standard），估计很多人都知道ISO 9001（质量管理体系）和ISO 14001（环境管理体系）等。ISO制定的汽车领域的电气/电子系统的“功能安全”国际标准就

AC/DC converters have the function of converting AC (alternating current voltage) to DC (direct current voltage).
Why are AC/DC converters needed?
Why are AC/DC converters needed? That's because the voltage received by residential homes and buildings is 100V or 200V AC voltage. However, most electrical appliances we use operate on 5V or 3.3V DC voltage. That is to say, if AC voltage is not converted to DC voltage, electrical appliances cannot operate.



Among them, there are also products such as motors and light bulbs that can be driven by AC voltage, but the control circuits of motors and microcontrollers...

Power semiconductor devices are the core of electrical energy conversion and circuit control in electronic devices, mainly used to change voltage and frequency, DC-AC conversion, etc., in electronic devices.

MOSFET (Metal-Oxide-Semiconductor field-effect transistor) is a common semiconductor device widely used in digital circuits, analog circuits, power electronics, and other fields. This article will explain the basic knowledge of MOSFET from aspects such as basic structure, working principle, and parameter characteristics.
1. Basic Structure of MOSFET
MOSFET is composed of three parts: Metal, Oxide, and Semiconductor. Its...

Classification by frequency: The most basic classification method. Diodes are classified according to their characteristics into rectifier diodes, switching diodes, Schottky barrier diodes, Zener diodes, and high-frequency diodes for high frequencies. Additionally, Zener diodes are generally used as protection components, but with the refinement of peripheral circuits and application miniaturization, higher-performance protection components — TVS (Transient Voltage Suppressor) are required.
 Classification by structure: Mainly divided into the current mainstream Planar type and mesa type for high voltage resistance.

The maximum requirement of 30 KV in JEDEC is because it is a common electrostatic discharge (ESD) voltage limit.
ESD is an electrostatic discharge that occurs between two objects, which may damage electronic equipment or cause data loss. Therefore, to ensure device reliability and stability, JEDEC established the 30 KV electrostatic discharge standard. This standard is based on actual testing and experience, ensuring that devices are not subject to unacceptable electrostatic discharge effects during normal operation and use.

JEDEC has established several standards for electrostatic discharge (ESD) in electronic chips, mainly including the following...

Overview of SiC Power Devices
