Its closest overlaps in the cited peer set are with StarPower, Silan Microelectronics, Macmic, and CR Micro in devices such as MOSFETs, IGBTs, SiC products, and power modules. Sanan and Wingtech broaden the comparison into compound semiconductors and more diversified semiconductor operations. The available filings identify companies and product overlaps, but do not support a current financial ranking or a single “best” supplier.
What Yangjie Technology makes
Yangzhou Yangjie Electronic Technology Co., Ltd. says it is an integrated device manufacturer, or IDM, combining discrete-semiconductor chip design and production with component assembly and testing, sales, and service. The company profile dates its founding to 2000 and its Shenzhen listing to January 23, 2014; its stock code is 300373. Yangjie also describes manufacturing arrangements that combine IDM and fabless approaches, so the IDM label should not be taken to mean every product follows an identical in-house production chain.

Its stated product scope includes discrete semiconductor chips, MOSFETs, IGBTs and power modules, silicon-carbide (SiC) products, rectifiers, protection devices, and small-signal products. The company lists automotive, AI, clean energy, industrial, 5G communications, smart homes, and consumer electronics among its application markets. That range makes Yangjie a broad power-device supplier rather than a company focused solely on one technology or end market.

How Yangjie describes its strategic priorities
In its 2025 annual report, Yangjie groups its businesses into three strategic categories. These are management’s classifications, not independent measures of sales contribution, market share, or technical leadership.
#1 Best Overall
- POWER MONITORING: Professional-grade current monitoring and power management evaluation board for precise power consumption analysis
- COMPATIBILITY: Designed specifically for Nordic Semiconductor development and testing applications
- MEASUREMENT CAPABILITIES: Enables real-time current measurement and power profiling for embedded system development
- DATA ANALYSIS: Features comprehensive power consumption data collection and visualization capabilities
- DEVELOPMENT TOOL: Essential evaluation board for optimizing power efficiency in embedded system projects and prototypes
| Company category | Businesses named by Yangjie | How to interpret it |
|---|---|---|
| H1: core business | Commercial standard devices, protection devices, photovoltaic diodes, rectifier modules, wafers, and silicon wafers | Products the company places in its core-business group |
| H2: growth business | MOSFETs and automotive electronics | Areas Yangjie identifies as growth businesses; the label alone does not establish their growth rate |
| H3: emerging business | SiC, IGBT, and logic ICs | Businesses Yangjie describes as emerging, not a measure of current scale or profitability |
The report also describes a dual-brand approach: YJ is emphasized in China and Asia-Pacific, while MCC is emphasized in Europe and the United States. Yangjie says it targets mid-to-high-end products and import substitution while facing strong international-brand competition. These are stated strategic aims rather than independent product-performance comparisons. Yangjie Technology 2025 annual report, published March 31, 2026
Which Chinese listed companies overlap with Yangjie?
An April 8, 2026 HKEX filing includes a valuation report with a set of listed semiconductor comparables. Its criteria included semiconductor-industry classification, established business or technology initiatives in SiC, comparable automotive-grade SiC products or competitor designation, R&D expenditure in each of the preceding three years, and available market and R&D data as of the valuation date. This is a valuation comparables set, not a definitive ranking of Chinese power-semiconductor companies. The overlap varies by product and application.

Yangjie’s 2025 annual report attributes global discrete-device market sales of US$30.9 billion in 2025 and an estimated US$33.44 billion in 2026 to WSTS. The 2026 figure is an estimate, and the attribution here is through Yangjie’s annual report rather than an independently reviewed WSTS release. These market-wide figures are context, not Yangjie sales or market share. Yangjie Technology 2025 annual report
The cited material does not provide consistently dated, comparable peer figures for revenue growth, margins, market share, or product-level competitiveness. A meaningful financial comparison would need each company’s latest primary filing and aligned periods, accounting bases, and segment definitions. The peer list and product descriptions alone cannot support a winner-or-loser ranking.

How to compare suppliers or stocks fairly
For procurement, industry research, or investment analysis, first decide which comparison matters. A supplier choice depends on a specific component and design requirement; an investment comparison depends on company-level financials and valuation, which are not established by product overlap alone.

- Match the product category: distinguish silicon discrete devices and rectifiers from MOSFETs, IGBTs, SiC devices, modules, and power ICs. Shared presence in a broad category does not mean identical products.
- Match the application: automotive, industrial control, renewable energy, EVs, appliances, communications, and consumer electronics have different product and qualification needs. A company’s listed markets do not prove that every product is suitable for each use.
- Check manufacturing scope: compare chip design, wafer production, assembly, testing, and sourcing arrangements for the specific product rather than assuming a company-wide label describes every line.
- For a stock comparison, align the evidence: use the same reporting period where possible, identify accounting and segment definitions, and separate company revenue from semiconductor-market estimates. Product breadth is not a substitute for profitability, growth, or valuation data.
- For a component decision, use part-level documentation: suitability of a power MOSFET transistor or other device depends on ratings, package, thermal conditions, and circuit requirements. Check the manufacturer’s authoritative datasheet and qualification information for the exact part.
