二極體：市場佔有率分析、產業趨勢與統計、成長預測（2026-2031）

二極體市場預計將從 2025 年的 181.6 億美元成長到 2026 年的 192.4 億美元，預計到 2031 年將達到 256.7 億美元，2026 年至 2031 年的複合年成長率為 5.95%。

儘管家用電子電器仍是二極體的最大終端用戶，市佔率達23.2%，但隨著全球電動車專案的加速推進，汽車應用領域正以6.8%的複合年成長率（CAGR）成為成長最快的領域。亞太地區佔全球營收的58.86%，年增率達6.63%，主要得益於中國、日本和韓國密集的製造群。表面黏著技術封裝佔出貨量的61.2%，而晶片級封裝的年複合成長率也高達7.1%，因為行動電話和物聯網製造商對封裝尺寸的要求越來越小。

全球二極體市場趨勢與洞察

家用電子電器生態系的數位化

智慧型手機、穿戴式裝置和連網家庭設備增加了每個系統中半導體的數量，從而推動了對用於訊號調理、電池保護和數據線保護的分立元件的需求。德克薩斯(TI) 的 ESDS31x 系列等小訊號靜電放電陣列可提供 ±30kV 的保護，資料傳輸速率高達 5Gbps，並支援 USB、HDMI 和乙太網路介面。亞太地區的製造商組裝了全球約 60% 的電子硬體，這支撐了對用於保護高速互連的二極體陣列的強勁需求。

加速電動車生產和車用充電器的普及

電動動力傳動系統的日益普及推動了對汽車半導體的需求。碳化矽和氮化鎵二極體可降低牽引逆變器和800V充電器中的開關損耗。安森美半導體的EliteSiC平台已被大眾汽車用於其下一代電動車。英飛凌的CoolSiC 1200V MOSFET使DC-DC級能夠在900V以上電壓下工作而無需額外的隔離，從而在降低系統成本的同時提高了功率密度。

原料價格波動（矽、砷化鎵、氮化鎵）

中國供應了大部分原生鎵原料，而出口限制導致砷化鎵（GaAs）和氮化鎵（GaN）裝置的晶圓成本飆升。全球僅20%的電子廢棄物妥善回收，造成關鍵金屬的流失，加劇了供應緊張和價格波動。碳化矽（SiC）晶圓的產量比率仍然不穩定，取決於製造技術的成熟度和基板品質。

細分市場分析

到2025年，雷射二極體將成為最大的二極體市場，規模達64.8億美元，年複合成長率（CAGR）為8.25%，主要受汽車頭燈、雷射雷達感測和高速光纖通訊等應用領域需求成長的推動。整流器和肖特基二極體將繼續在功率轉換領域佔據一席之地，但其成長率將處於個位數中段，低於雷射二極體的普及速度。

工業切割、投影機和3D列印將推動對多模雷射二極體的需求，而醫用雷射則需要更嚴格的波長穩定性，從而推高平均售價。在伺服器電源領域，英飛凌的氮化鎵電晶體正與肖特基二極體整合，以減少死區時間損失並提高效率，這為跨領域合作提供了一個良好的範例。

區域分析

亞太地區預計到2025年將佔全球收入的58.30%，並在2031年之前保持6.45%的複合年成長率，這主要得益於中國、日本和韓國一體化的供應鏈。 2023年，中國在全球晶片銷售中佔據了絕大部分佔有率，這得益於政府激勵措施和國內智慧型手機出口的成長。印尼透過發放98張矽砂開採許可證和提供稅收優惠政策，吸引了外國投資者，旨在實現基板生產的在地化。

預計到2030年，北美市場佔有率將有所成長。 《晶片技術創新法案》（CHIPS Act）的津貼預計將促成5,400億美元的私人晶圓廠投資，其中包括安森美德克薩斯州）在德州新建的8吋碳化矽（SiC）生產線。加拿大正透過清潔技術稅額扣抵來支持氮化鎵（GaN）外延晶圓新興企業，以建立增值流程。墨西哥的電子製造服務（EMS）叢集正在擴大對美國汽車供應鏈的免稅准入，從而促進整流器和突波保護裝置的組裝。

歐洲的目標是到2030年佔據全球20%以上的產量，但審核顯示，由於核准延誤和技術純熟勞工短缺，進度面臨風險。 Nexperia在漢堡投資2億美元將擴大歐洲碳化矽（SiC）產能，而波蘭將設立英特爾後晶圓廠測試中心，創造2,000個工作機會。中東和非洲地區仍處於低度開發狀態，但採用1200V碳化矽二極體的太陽能逆變器試點工廠已在阿拉伯聯合大公國運作。

第7章 市場機會與未來展望

The diode market is expected to grow from USD 18.16 billion in 2025 to USD 19.24 billion in 2026 and is forecast to reach USD 25.67 billion by 2031 at 5.95% CAGR over 2026-2031.

Consumer electronics remains the largest end-user at 23.2% diode market share, while automotive applications show the strongest 6.8% CAGR as electric-vehicle programs accelerate worldwide. Asia-Pacific holds 58.86% of global revenue and grows at a 6.63% pace thanks to dense manufacturing clusters in China, Japan, and South Korea. Surface-mount packaging captures 61.2% of shipments, yet chip-scale packages rise at a 7.1% CAGR because handset and IoT producers need ever-smaller footprints.

Global Diode Market Trends and Insights

Digitization of Consumer Electronics Ecosystems

Smartphones, wearables, and connected-home devices embed higher semiconductor content per system, lifting discrete component volumes for signal conditioning, battery protection, and data-line safeguarding. Small-signal and electrostatic-discharge arrays such as the ESDS31x series from Texas Instruments deliver +-30 kV protection at up to 5 Gbps data rates, supporting USB, HDMI, and Ethernet interfaces.Asia-Pacific manufacturers assemble about 60% of global electronics hardware, feeding clustered demand for diode arrays that secure high-speed interconnects.

Acceleration of EV Production and On-Board Chargers

Automotive semiconductor demand is increasing as electric-powertrain penetration climbs. Silicon-carbide and gallium-nitride diodes deliver lower switching losses for traction inverters and 800 V chargers; onsemi's EliteSiC platform has been adopted by Volkswagen for next-generation EVs.Infineon's CoolSiC 1200 V MOSFETs allow DC-DC stages to operate beyond 900 V without extra insulation, raising power density while trimming system cost.

Raw-Material Price Volatility (Si, GaAs, GaN)

China provides most primary gallium feedstock, and any export curbs rapidly elevate wafer costs for GaAs and GaN devices. Only 20% of global e-waste is properly recycled, causing critical-metal losses that tighten supply and raise pricing swings. SiC wafer yields remain volatile, contingent on manufacturing maturity and substrate quality.

Other drivers and restraints analyzed in the detailed report include:

1. 5G Rollout Boosting RF and Microwave Diodes
2. Data-Center Efficiency Mandates Raising Power-Diode Demand
3. Thermal Limitations in High-Current Packages

Segment Analysis

Laser diodes generated the largest diode market size at USD 6.48 billion in 2025 and are positioned for an 8.25% CAGR, propelled by automotive front-lighting, LiDAR sensing, and high-speed fiber communications. Rectifier and Schottky devices continue to secure power-conversion sockets, though their mid-single-digit growth trails laser adoption.

Industrial cutting, projectors, and 3D printing sustain multimode laser-diode volumes, while medical-grade lasers require tighter wavelength stability that lifts average selling prices. In server power supplies, Infineon's GaN transistors integrate a Schottky diode that curbs dead-time losses and elevates efficiency, showcasing cross-category partnerships.

The Diode Market Report is Segmented by Product Type (Schottky Diodes, Zener Diodes, and More), End-User Industry (Communications, Consumer Electronics, Automotive, Defense and Aerospace, Computer and Peripherals, and More), Mounting-Package (Through-Hole, Surface-Mount, and More), and Geography (North America, South America, Europe, Asia-Pacific, Middle East and Africa). The Market Forecasts are Provided in Terms of Value (USD).

Geography Analysis

Asia-Pacific held 58.30% of global revenue in 2025, and continues at a 6.45% CAGR through 2031 on the back of integrated supply chains in China, Japan, and South Korea. China absorbed a significant share of world chip sales in 2023, buoyed by government incentives and domestic smartphone exports. Indonesia courts foreign investors with 98 silica-sand mining licenses and tax holidays, aiming to localize substrate production.

North America's share is set to rise by 2030 as the CHIPS Act grants unlock USD 540 billion of private fab commitments, including onsemi's new 8-inch SiC line in Texas. Canada supports GaN epi-wafer startups through Clean-Tech credits, seeking to anchor value-add processes. Mexico's EMS clusters extend tariff-free access to the U.S. vehicle supply chain, stimulating rectifier and transient-voltage-suppressor assembly.

Europe targets more than 20% global production share by 2030, though audit findings warn of schedule risk given permitting delays and skilled-labor gaps. Nexperia's USD 200 million Hamburg investment broadens European SiC capacity, while Poland secures Intel's post-fab testing center that creates 2,000 roles. The Middle East and Africa remain nascent but see pilot solar-inverter fabs in the UAE that specify 1200 V SiC diodes.
