Its broad discrete-device portfolio and IDM positioning distinguish its scope; StarPower and Macmic are more centered on power modules and higher-power applications, while Silan and CR Micro span power devices alongside wider semiconductor businesses. A Hong Kong-listed-company valuation report identifies these firms as comparables, not as a ranking of market leaders.
What Yangjie Technology makes
Yangzhou Yangjie Electronic Technology Co., Ltd. describes itself as an integrated device manufacturer (IDM) covering semiconductor chip design and production, component assembly and testing, sales, and service. The company says it was founded in Yangzhou in 2000 and listed in Shenzhen on January 23, 2014. Its profile lists discrete semiconductor chips, MOSFETs, IGBT and power modules, SiC devices, rectifiers, protection devices, and small-signal products. It names automotive, AI, clean energy, industrial, 5G communications, smart-home, and consumer-electronics markets among its end markets. Yangjie Technology’s company profile calls its mission to “Be a Reliable Solutions Partner in Power Semiconductor to Global Customers.”

IDM is Yangjie’s own description, not a claim that every product follows an identical in-house manufacturing route. The company has also described approaches combining IDM and fabless models, so production scope can vary by product.

How Yangjie groups its businesses
In its 2025 annual report, Yangjie divides its portfolio into three strategic groups. The labels indicate management’s stated priorities; they do not independently establish market share, earnings contribution, 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 grouping | Products and businesses named |
|---|---|
| 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 same report describes a dual-brand strategy: YJ is emphasized in China and Asia-Pacific, and MCC in Europe and the United States. It says Yangjie targets mid-to-high-end products and import substitution while facing strong international-brand competition. These are company-stated strategic aims, not independently verified comparisons of product performance. Yangjie’s 2025 annual report, published March 31, 2026, also cites WSTS figures of US$30.9 billion in global discrete-device sales for 2025 and a US$33.44 billion estimate for 2026. Those market figures are attributed to WSTS by Yangjie; the 2026 value is an estimate, not a realized result.
Which Chinese companies overlap with Yangjie?
An April 8, 2026 HKEX filing includes a valuation report that selected listed semiconductor comparables using criteria that included semiconductor-industry classification, SiC-related business or technology initiatives, comparable automotive-grade SiC products or competitor status, R&D spending in each of the prior three years, and available market and R&D data at the valuation date. The resulting set is useful for identifying comparison candidates, but its inclusion criteria do not show that all firms compete directly with Yangjie in every product category.

Where the comparisons are strongest—and where they differ
Discrete devices and rectifiers
Yangjie explicitly identifies discrete devices, rectifiers, protection products, and small-signal products in its portfolio, making its scope broader than a comparison limited to IGBTs or modules. Silan, CR Micro, and Wingtech also describe businesses extending across multiple semiconductor categories. A broad product label, however, does not establish that two companies offer interchangeable parts: device ratings, package, process, and datasheet specifications determine suitability for a design.
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.
MOSFETs, IGBTs, SiC, and modules
There is meaningful category overlap with StarPower, Silan, Macmic, CR Micro, and Wingtech in one or more of these areas. StarPower and Macmic’s cited descriptions emphasize chips and modules for power applications; Yangjie’s report places MOSFETs in its growth group and IGBT and SiC in emerging businesses. This is a difference in disclosed strategic grouping, not evidence that one supplier is technically or commercially ahead.
End markets and vertical scope
Automotive, industrial, and energy applications recur across the peer set, while appliances and consumer electronics appear in several company descriptions. Yangjie additionally names communications, smart homes, and AI among its served markets. The available descriptions do not quantify sales by end market consistently, so breadth of listed applications should not be mistaken for comparable exposure or revenue dependence.

What the available numbers can—and cannot—show
The January 27, 2026 HKEX valuation-report summary shows Yangjie revenue composition as 86.2474% semiconductor devices, 8.3270% semiconductor chips, 3.0766% semiconductor silicon wafers, and 2.3490% other business. These percentages total 100% in that filing’s reporting context. They describe Yangjie’s mix, not its competitors’ mix or the share of any product in the Chinese market.
The cited filings do not provide a consistently dated, comparable set of revenue growth, margins, market shares, or product-level sales for Yangjie and all named peers. A financial league table would require aligned reporting periods, accounting bases, and comparable business definitions from each company’s primary filings. The HKEX peer list is a valuation-comparables set, not a market-share table, and it does not support declaring a winner or loser.

How to use this comparison when choosing a supplier
For procurement or design work, begin with the part and application rather than the company name. Compare candidate suppliers using the same evidence for each:
Quick Recap
- Product category: establish whether the requirement is a silicon discrete device, MOSFET, IGBT, SiC component, module, or IC.
- Electrical and thermal fit: check the exact datasheet ratings, package, operating conditions, and circuit requirements before treating parts as substitutes.
- Manufacturing scope: verify which production steps and facilities apply to the specific product; an IDM label alone does not settle that question.
- Application evidence: distinguish a market listed in a company profile from demonstrated qualification or suitability for a particular design.
- Business comparison: for financial or strategic analysis, align each company’s reporting period, accounting basis, product definitions, and source date.
Product prices and availability are accurate as of the date/time indicated and are subject to change. Any price and availability information displayed on Amazon at the time of purchase will apply.
