根據 Mordor Intelligence 預測,功率電晶體市場規模將從 2025 年的 213.8 億美元成長到 2026 年的 226.3 億美元,然後在 2031 年達到 300.7 億美元,2026 年至 2031 年的複合年成長率為 5.86%。

本報告按產品(例如,低壓場效電晶體)、材料(例如,矽)、類型(例如,雙極電晶體)和封裝(例如,分立元件)進行分類。此外,還按功率等級(例如,低功耗(低於 40 V))、終端用戶行業(例如,資料中心和高效能運算)、應用(例如,逆變器和轉換器)以及地區進行分類。市場預測以美元計價。
在400V和800V牽引逆變器中,SiC MOSFET正在取代矽IGBT。這是因為SiC MOSFET可以將組件重量減輕40%,體積縮小30%,並透過降低開關損耗來擴展工作範圍。意法半導體計畫於2025年將其第四代STPOWER SiC MOSFET商業化,該產品支援上述兩種電壓等級。意法半導體與賽米光簽署了一份價值10億歐元的契約,從2025年起向德國汽車製造商供應SiC eMPack模組,這構成了長期需求的基礎。中國、日本和韓國的汽車製造商也正在採用自主研發的SiC模組,並加強與基板製造商的合作。隨著組裝產量的增加,學習曲線帶來的成本降低正在部分抵銷目前SiC晶圓較高的成本。
5G大型基地台和小型基地台無線電設備的部署計畫催生了對高效能射頻前端的迫切需求。在新無線架構中,高電子移動性電晶體 HEMT)因其能夠在不影響線性度的前提下處理寬頻頻寬和高汲極電壓,而優於LDMOS和GaAs。 Wolfspeed的28V、30W GaN HEMT晶片工作頻率高達8GHz,符合通訊和衛星規格以及NASA可靠性標準。亞太地區的通訊業者,尤其是中國和韓國,仍是主要需求來源。隨後,北美地區也開始部署中頻寬設備,並制定了嚴格的效率目標以降低站點級功耗。隨著專用網路和衛星網際網路的部署即將到來,對射頻GaN裝置的需求將持續成長。
即使自2024年以來已宣布新建14座200毫米碳化矽晶圓廠,也無法緩解過去十年持續存在的晶圓短缺問題。有限的晶錠(晶體)良率推高了外延晶圓的價格,增加了功率模組的物料清單(BOM),並減緩了其在對成本敏感的太陽能和工業逆變器領域的應用。義法半導體(STMicroelectronics)正在卡塔尼亞投資50億歐元建造一座完全整合的碳化矽工廠,目標是到2033年實現每週15,000片晶圓的產量。與英飛凌(Infineon)和Wolfspeed等公司簽訂的多年期晶圓供應協議,例如擴大合約規模,暫時緩解了供應緊張的局面,但預計在200毫米晶體生長技術成熟之前,供應緊張的局面仍將持續。
到2025年,MOSFET將佔總銷售額的45.55%,這表明其應用範圍已從行動電話充電器擴展到工業驅動器等各個領域。寬能隙功率電晶體市場預計將從2026年的85.3億美元成長到2031年的124.9億美元,複合年成長率(CAGR)為7.95%。英飛凌推出的「CoolGaN G5」進一步推動了氮化鎵(GaN)的發展,該產品採用了蕭特基二極體來減少死區時間和電磁干擾(EMI)。
儘管牽引逆變器和工業驅動器對IGBT的需求持續成長,但隨著SiC產品選擇的增多,成長速度正在放緩。超接面MOSFET憑藉其成熟的供應鏈和成本優勢,在中壓伺服器市場保持領先地位。隨著GaN在高功率應用領域取代GaAs,射頻和微波電晶體在通訊和衛星鏈路領域實現了強勁成長。
儘管矽在2025年佔了70.40%的出貨量佔有率,但氮化鎵(GaN)的銷售額預計將以9.45%的複合年成長率成長,成為所有材料中成長最快的。氮化鎵功率電晶體的市佔率預計將在2025年超過7.25%,並在2031年達到約10%的滲透率。消費性快速充電器、馬達驅動裝置和48V資料中心電源軌是其初期需求的主要來源。
碳化矽在電動車、太陽能和儲能等600V以上的應用領域仍有優勢。市場領導者意法半導體(STMicroelectronics)在2024年佔據了碳化矽元件市場32.6%的佔有率。氧化鎵等新興材料目前仍處於早期提案階段,但它們凸顯了材料科學領域持續不斷的創新。
由於能夠高效擴展且不受電壓等級限制的功率 MOSFET 的出現,場效應 (FET) 架構預計在 2025 年將佔據 61.30% 的市場佔有率。隨著設計轉向寬能隙(WBG) 平台,FET 功率電晶體市場預計將穩定成長。異質接面雙極電晶體 (HJT) 雖然市佔率較小,但在毫米波 5G 和低地球軌道衛星有效載荷等領域,其應用正迅速發展,因為這些應用對高頻效率要求極高。
雙極結型裝置仍應用於傳統的工業控制領域,在這些領域,穩健性比開關速度更為重要。結合GaN閘極驅動器和SiC MOSFET輸出級的混合拓樸結構的出現,標誌著設計方法正朝著以系統為中心的最佳化方向轉變。
到2025年,亞太地區將佔全球功率電晶體市場收入的51.40%,繼續保持其在銷售方面的絕對領先地位。中國電動車產量的激增,以及國內碳化矽(SiC)和氮化鎵(GaN)晶圓廠的擴張,正在鞏固整個供應鏈的需求。日本和韓國正在擴大高附加價值汽車和消費性電子裝置的設計和應用,而印度則在其「半導體使命」的指導下加快對晶圓代工廠的投資。意法半導體(STMicroelectronics)與三安半導體(Sanan)合資生產200毫米碳化矽(SiC)晶圓,正是該地區致力於寬能隙(WBG)技術局部化的典型例證。泰國2024年積體電路進口量成長27%,顯示全部區域正在持續推進一體化進程。
北美和歐洲合計約佔全球市場佔有率的40%,其基礎主要集中在汽車電力電子、資料中心基礎設施和工業自動化領域。美國《晶片與整合產品法案》(CHIPS Act)的獎勵正在推動新一輪碳化矽(SiC)和氮化鎵(GaN)晶圓廠的發展,優先保障汽車和國防領域的供應鏈韌性。歐洲的《關鍵材料法案》(Critical Materials Act)和創新計劃,重點關注直流-直流轉換器、固態變壓器和電池模組,正在強化電力電子價值鏈。這兩個地區都在積極推進技術合作,以促進200毫米碳化矽晶體生長和無缺陷氮化鎵外延技術的發展。
中東和非洲地區雖然規模較小,卻是成長最快的市場,預計到2031年複合年成長率將達到8.45%。諸如「沙烏地阿拉伯2030願景」和阿拉伯聯合大公國G42半導體促進計畫等國家級計畫正在推動對可再生能源逆變器、資料中心叢集和電動車充電走廊的投資。充足的陽光和優惠的電價自然促進了高壓碳化矽元件的應用,而當地的設計中心也吸引著來自海外的工程師。
According to Mordor Intelligence, the power transistor market size is expected to grow from USD 21.38 billion in 2025 to USD 22.63 billion in 2026 and is forecast to reach USD 30.07 billion by 2031 at 5.86% CAGR over 2026-2031.

SiC MOSFETs are displacing silicon IGBTs in 400 V and 800 V traction inverters because they deliver 40% lighter, 30% smaller assemblies and cut switching losses, which extends driving range. STMicroelectronics plans to commercialize fourth-generation STPOWER SiC MOSFETs in 2025, tailored for both voltage classes. A billion-euro supply deal between ST and Semikron covering SiC eMPack modules for a German automaker from 2025 anchors long-term demand. Chinese, Japanese, and South Korean OEMs are likewise integrating captive SiC modules, tightening ties with substrate makers. As assembly volumes rise, learning-curve savings partially offset today's SiC wafer premiums.
Roll-out timelines for 5G macro and small-cell radios drive urgent need for high-efficiency RF front ends. GaN high-electron-mobility transistors (HEMTs) handle wide bandwidth and high drain voltages without compromising linearity, making them preferred over LDMOS or GaAs in new radio architectures. Wolfspeed's 28 V, 30 W GaN HEMT die operates to 8 GHz, meeting telecom and satellite specifications while satisfying NASA reliability metrics. Asia-Pacific carriers, particularly in China and South Korea, remain the volume anchors; North America follows with mid-band deployments that stipulate stringent efficiency targets to curb site-level power bills. With private-network and satellite-internet roll-outs ahead, RF GaN remains on an upward curve.
Fourteen 200 mm SiC fabs announced since 2024 remain insufficient to eliminate the wafer deficit through the decade. Limited boule yields raise epitaxial wafer prices and inflate power-module bills of material, slowing adoption in cost-sensitive solar and industrial inverters. STMicroelectronics is investing EUR 5 billion in Catania to create a fully integrated SiC complex, aiming for 15,000 wafers/week by 2033. Multi-year wafer-supply agreements, such as Infineon-Wolfspeed's expanded pact, partially buffer availability, yet supply tightness persists until 200 mm crystal growth matures.

MOSFETs contributed 45.55% of revenue in 2025, underscoring their ubiquity from handset chargers to industrial drives. The power transistor market size for wide-bandgap power transistors is projected to climb from USD 8.53 billion in 2026 to USD 12.49 billion by 2031, translating to an 7.95% CAGR. GaN gets a further boost from Infineon's CoolGaN G5 launch that embeds a Schottky diode, trimming dead-time and EMI.
Demand for IGBTs in traction inverters and industrial drives still rises, yet at a tempered rate as SiC options proliferate. Super-junction MOSFETs defend medium-voltage servers thanks to mature supply lines and cost position. RF & microwave transistors record healthy gains from telecom and satellite links as GaN displaces GaAs for higher-power services.
Silicon accounted for 70.40% of 2025 shipments, but GaN revenue is forecast to expand at a 9.45% CAGR, the steepest across materials. The power transistor market share for GaN surpassed 7.25% in 2025 and is on track to achieve low-teens penetration by 2031. Consumer fast-chargers, motor drives, and 48 V data-center rails form the early-majority demand pool.
SiC's stronghold remains applications above 600 V in EVs, solar, and storage. Market leader STMicroelectronics held 32.6% of SiC device revenue in 2024. Emerging candidates such as gallium oxide remain early-research propositions, yet they highlight ongoing material-science innovation.
Field-effect architectures captured 61.30% of 2025 revenue because power MOSFETs scale efficiently across voltage grades. The power transistor market size for FETs is set to expand steadily as design-ins migrate toward WBG platforms. Heterojunction bipolar transistors, though smaller, gain momentum in millimeter-wave 5G and low-Earth-orbit satellite payloads that prize high-frequency efficiency.
Bipolar-junction devices persist in legacy industrial controls where robustness trumps switching speed. Hybrid topologies that marry GaN gate drivers with SiC MOSFET output stages are surfacing, signaling convergent design approaches that favor system-centric optimization.
Asia Pacific generated 51.40% of power transistor market revenue in 2025 and holds undisputed volume leadership. China's EV output surge, combined with expanding domestic SiC and GaN fabs, cements demand across the supply chain. Japan and South Korea add high-value automotive and consumer-device design-ins, while India accelerates foundry investments under its semiconductor mission. Joint ventures such as STMicroelectronics-Sanan for 200 mm SiC production exemplify the region's bid to localize WBG capability. Thailand's 27% rise in integrated-circuit imports during 2024 signals broader regional integration.
North America and Europe jointly account for about 40% of the market, anchored in automotive power electronics, data-center infrastructure, and industrial automation. U.S. CHIPS Act incentives underpin a new wave of SiC and GaN fabs that prioritize automotive and defense supply resilience. Europe's Critical Raw Materials Act and innovation programs target DC-DC converters, solid-state transformers, and battery modules, reinforcing its power electronics value chain. Both regions cultivate technical partnerships to advance 200 mm SiC crystal growth and zero-defect GaN epitaxy.
The Middle East & Africa represent a small but fastest-growing slice, with an 8.45% CAGR forecast to 2031. National programs such as Saudi Vision 2030 and the UAE's G42 semiconductor push channel investment into renewable energy inverters, data-center clusters, and EV charging corridors. Abundant solar irradiation and favorable power tariffs provide a natural pull for high-voltage SiC device deployment, while local design hubs attract diaspora engineering talent.
