GDT Gas Discharge Tube, also known as gas discharge tube or overvoltage protection tube, is a passive electronic component used to protect circuits from overvoltage and surge voltage effects. It can achieve suppression of high-voltage interference and current puncture through gas discharge. The following are the working principle and application occasions of GDT gas discharge tubes: 1. Working Principle
GDT gas discharge tubes utilize the characteristics of gas discharge to achieve overvoltage protection for circuits. When overvoltage or overcurrent exists in the circuit, the GDT gas discharge tube forms a low impedance path, reducing the voltage to a safe level. During the gas discharge process, the resistance of the GDT rapidly decreases, a spark appears, followed by gas discharge or even arc light. Only after the overvoltage disappears will the GDT return to a high impedance state. 2. Application Occasions
GDT gas discharge tubes are widely used in overvoltage protection for various electronic devices, including telecommunications, communications, power, computers, industrial control, and other fields. Specific application occasions are as follows: (1) Power and communication line protection: GDT gas discharge tubes are applied in power and communication systems to protect various lines, avoiding damage to lines and equipment caused by high voltage surges. (2) High voltage power supply protection: GDT gas discharge tubes protect circuits in high voltage power supplies from overvoltage, surge, and other transient interference. (3) Industrial control protection: GDT gas discharge tubes are used to protect various industrial control equipment, such as PLC, DCS, etc., avoiding damage caused by line interference. (4) Fire alarm system protection: GDT gas discharge tubes are used in fire alarm systems to protect the system from static interference and lightning strikes. (5) LED light protection: GDT gas discharge tubes are used in LED lights to protect LEDs from overvoltage and surge voltage effects, thereby extending their lifespan. In summary, GDT gas discharge tubes are important components for protecting circuits, protecting various lines from overvoltage and surge voltage effects, improving system stability and reliability.

PPTC self-recovery fuse working principle and application precautions?         The working principle of PPTC self-recovery fuse is based on the positive temperature coefficient property of the material. Under normal working temperature, the fuse material is in a low resistance state; once the current exceeds the rated value, the internal temperature of the fuse increases, causing the material to enter a high resistance state, limiting current flow, preventing equipment damage or fire caused by overcurrent. However, once the current drops to a safe range, the internal temperature of the fuse decreases, the material returns to a low resistance state, restoring normal power state. PPTC self-recovery fuse application precautions are as follows: 1. Fully understand the working conditions of the protected circuit and select the appropriate fuse rated voltage and current values. 2. Avoid mechanical or other physical factors causing damage to the fuse, leading to failure or inability to self-recover. 3. During installation, avoid the fuse being in high-temperature environments or subjected to excessive vibration to prevent premature fuse failure or interference with self-recovery. 4. For fuses that need replacement, must select fuses with the same specifications and performance for replacement. 5. For infrequently used circuit equipment, regularly check the status and function of the fuse to ensure it can work normally when needed.

The TSS (Transient Suppressing Semiconductor) diode, also known as the TVS diode, is a passive electronic component used to protect electronic devices. It can limit the amplitude and slope of transient voltage spikes, thereby protecting other components in the circuit from voltage transients.

The ESD (Electrostatic Discharge) diode is a passive electronic component used to protect electronic devices. It is also referred to as an ESD electrostatic protector. It can effectively limit the damage caused by electrostatic discharge (ESD) to circuits, preventing damage, malfunction, or failure caused by static electricity. The following provides a detailed explanation of the product characteristics and applications of the ESD diode:

According to reports, the national standard "Reference Architecture for Blockchain and Distributed Accounting Technology" (GB/T 42752-2023) has recently been officially released. This is the first national standard in the field of blockchain technology approved for publication in China.

Recently, according to news from the Institute of Semiconductors, Chinese Academy of Sciences, the Microwave Photonics Group of the State Key Laboratory of Integrated Optoelectronics, researcher Li Ming's team and academician Zhu Ninghua's team developed an ultra-high integration optical convolution processor. Related research results were published in the journal Nature Communications with the title "Compact optical convolution processing unit based on multimode interference."
Convolutional Neural Networks (CNNs) are artificial neural networks inspired by the biological visual nervous system, consisting of multiple convolutional layers, pooling layers, and fully connected layers. As the core component of convolutional neural networks, convolutional layers extract features of different levels and abstraction degrees through local perception and weight sharing of input data. In a complete convolutional neural network, convolution operations usually account for over 80% of the entire network's computational load. Although convolutional neural networks have achieved great success in fields such as image recognition, they also face huge challenges. Traditional convolutional neural networks are mainly implemented based on von Neumann architecture electronic hardware, where storage units and processing units are separate, leading to inherent contradictions between data exchange speed and energy consumption. As data volume and network complexity increase, electronic computing solutions are increasingly unable to meet the demand for high-speed, low-energy computing hardware for real-time processing of massive data.

Optical computing is a technology that uses light waves as carriers for information processing. It has advantages such as large bandwidth, low latency, and low power consumption, providing a computing architecture of "transmission is computation, structure is function," which is expected to avoid data tidal transmission issues existing in the von Neumann computing paradigm. Optical computing has received widespread attention in recent years, but in most reported optical computing schemes, the number of optical components grows quadratically with the scale of the computing matrix, posing huge challenges to the scaling of optical computing chips.

According to foreign media reports, under pressure from the United States, China will launch a large-scale plan to support its semiconductor industry in order to achieve self-sufficiency in chips. Sources have revealed in detail China's next steps. According to foreign media reports on Tuesday (December 13th), three sources said that China is developing a support plan worth over 1 trillion yuan (143 billion US dollars) to support the development of the semiconductor industry. According to sources, this is one of the largest fiscal incentive plans planned by the Chinese government within the next five years, mainly to support domestic semiconductor production and research and development through subsidies and tax credits.
