A diode is an electronic component made from semiconductor materials like silicon, selenium, or germanium, designed to control the direction of current flow. As one of the earliest semiconductor devices, diodes are widely used across various applications, including rectification, voltage regulation, and signal modulation.
Currently, the production and export of diodes are concentrated in the Asia-Pacific and parts of North America and Europe, notably in countries such as China, South Korea, Japan, the United States, and Germany. These regions leverage their well-established industrial chains, advanced technology, production capacity, and significant market size, making them key production and export hubs. From a demand perspective, the Asia-Pacific, North America, and Europe represent the largest diode consumption markets, with demand also rising in emerging markets like India, Southeast Asia, and Latin America.
In Southeast Asia, Vietnam's demand for diodes has grown steadily, driven by advancements in electronics manufacturing and expanding sectors like consumer electronics, telecommunications, and automotive electronics. Vietnam’s domestic diode production capacity is low, and the country relies heavily on imports to meet its market demand.
According to CRI, Vietnam imported diodes worth approximately USD 429 million in 2023, with import demand increasing in 2024 as imports from January to June reached USD 271 million. This upward trend in imports is expected to continue due to limited local production capacity.
CRI data shows that Vietnam's primary diode import sources include China, Singapore, the United States, Japan, and South Korea. South Korea and China, with their complete supply chains and competitive product prices, are notable suppliers.
Based on CRI’s analysis, from 2021 to 2024, the top import origins for Vietnam's diode market were South Korea, Hong Kong (for re-export trade), and China. Key exporters to Vietnam include companies like DONG YANG E&P INC, CLOUD NETWORK TECHNOLOGY SINGAPORE, and LG ELECTRONICS INC.
Vietnam’s primary importers of diodes are electronics manufacturers and distributors, including FUNING PRECISION COMPONENT CO LTD, LG ELECTRONICS VIETNAM HAI PHONG, and GOERTEK TECHNOLOGY VINA CO LTD.
As Vietnam’s electronics industry grows, the demand for diodes will likely continue to rise, with diodes remaining essential components in electronic circuits. CRI expects Vietnam’s diode imports to grow in the coming years due to ongoing electronics industry development and expanding application areas in downstream industries.
