What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Yangjie Technology (SZSE: 300373) overlaps with several Chinese-listed semiconductor companies, but the overlap depends on the product: it spans discrete devices, MOSFETs, IGBTs, power modules and SiC. StarPower and Macmic are closer comparisons for power modules and IGBT/SiC; Silan and CR Micro cover broader mixes of power devices and ICs; Wingtech has a wide semiconductor portfolio, while Sanan is relevant chiefly to compound semiconductors. An HKEX valuation report names these companies as comparables, not as a definitive ranking or proof that they compete directly in every market.
What Yangjie Technology makes
Yangzhou Yangjie Electronic Technology Co., Ltd. describes itself as an integrated device manufacturer (IDM), combining semiconductor chip design and production with component assembly and testing, sales, and service. Its official profile says it was founded in Yangzhou in 2000, listed in Shenzhen on January 23, 2014, and trades as stock code 300373. The company also describes manufacturing approaches that combine IDM and fabless models, so the IDM label should not be read as meaning every product follows the same production arrangement. Yangjie Technology company profile
The listed portfolio includes discrete semiconductor chips, MOSFETs, IGBT and power modules, SiC, rectifiers, protection devices, and small-signal products. Yangjie names automotive, AI, clean energy, industrial, 5G communications, smart homes, and consumer electronics among its markets. That breadth makes “competitor” a product-specific term: a company may overlap in MOSFETs or SiC without matching Yangjie’s full device range or market exposure.
How Yangjie groups its businesses
In its 2025 annual report, Yangjie classifies its portfolio as core (H1), growth (H2), and emerging (H3). These are management’s strategic categories, not independent measurements of revenue contribution, market share, or technical position.
#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 | Products named in Yangjie’s 2025 annual report |
|---|---|
| H1: core business | Commercial standard devices, protection devices, photovoltaic diodes, rectifier modules, wafers, and silicon wafers |
| H2: growth business | MOSFETs and automotive electronics |
| H3: emerging business | SiC, IGBT, and logic ICs |
The report also describes a dual-brand strategy: 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. Those statements describe company strategy; they do not establish comparative product performance. Yangjie Technology 2025 annual report, published March 31, 2026
Which Chinese companies overlap most with Yangjie?
An April 8, 2026 HKEX filing includes a valuation report with a selected 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 status, R&D spending in each of the preceding three years, and market and R&D data available as of the valuation date. This is a valuation peer set, not an industry league table; the degree of overlap varies by product and application. HKEX filing and appended valuation report, April 8, 2026

How to compare the companies for a real decision
For supplier evaluation, investment research, or industry analysis, compare the companies on aligned dimensions rather than treating the peer list as a ranking:
- Product family: Separate silicon discrete devices and rectifiers from MOSFETs, IGBTs, SiC devices, modules, and ICs. Shared labels do not show that products have identical ratings, packages, performance, or qualification status.
- End market: Check the application that matters—such as automotive, industrial control, renewable energy, appliances, communications, or consumer electronics. Broad market lists are not evidence of equal exposure.
- Manufacturing scope: Distinguish chip design and fabrication from assembly, testing, module production, and other business lines. A company-level label alone does not explain how a specific product is manufactured.
- Evidence period and basis: For financial comparisons, align reporting periods, accounting basis, currency, and source dates, and compare the same business scope. The cited material does not provide consistently dated figures for all companies that would support a current ranking by growth, margins, or market share.
For a component design or purchasing decision, compare the exact part’s datasheet against the circuit’s voltage and current requirements, switching behavior, package, thermal conditions, and qualification needs. A company-level product category cannot establish that a particular component is suitable.
Rank #3
- Complete and practical package: The package contains more than 400 components, which can help you complete interesting and simple electrical experiments.
- Clear and sturdy packaging: Each component is classified and packaged and placed in a transparent box with clear labels on it, making it easy to find components.
- Humanized design: The package includes a power module and a USB data cable, and the components can be directly plugged into the breadboard, which is more convenient without soldering.
- The quality of components is reliable.
- Compatible with STM32,Raspberry Pi,Arduino and so on.
What the available market and revenue figures do—and do not—show
An HKEX valuation-report summary dated January 27, 2026, presents Yangjie’s revenue composition as 86.2474% semiconductor devices, 8.3270% semiconductor chips, 3.0766% semiconductor silicon wafers, and 2.3490% other business. These percentages describe the composition shown in that filing summary; they do not compare Yangjie with peers or identify product-level market shares. HKEX valuation-report summary, January 27, 2026
Yangjie’s 2025 annual report attributes to WSTS global discrete-device market sales of US$30.9 billion in 2025 and an estimated US$33.44 billion for 2026. The latter is an estimate, not a reported final market result. These category-level figures provide context for the market Yangjie discusses, not evidence that Yangjie or any named peer holds a particular share or is growing faster.
