Introduction: Amid the surge in industrial automation and new energy vehicles, digital isolators have become indispensable core components. Shenzhen Mingjiada Electronics Co., Ltd. (hereinafter referred to as “Mingjiada”) recently announced that, in response to global supply chain fluctuations and inventory backlogs resulting from the chip shortage, it will expand its digital isolator recycling business. Leveraging its channel advantages cultivated over decades in the industry, the company aims to help global customers optimize their cash flow and achieve the efficient recycling of isolation chips from various brands.
Market Background: Why Have Digital Isolators Become a “Hot Commodity” for Recycling?
Digital isolators are primarily used in industrial control, new energy vehicles, communication power supplies, and photovoltaic energy storage. As industry giants such as Nano Micro Semiconductor continue to acquire and integrate digital isolator technologies, technological iteration in this field has accelerated, leading to significant amounts of idle inventory among some end customers.
As a seasoned electronic component service provider established in 1996, Mingjiada leverages its global logistics network (Shenzhen, Hong Kong, Japan) to conduct long-term bulk purchases of the following mainstream global digital isolator brands.
Purchase List: Brands and Series of Focus for Mingjiada
If your inventory includes the following brands or products, please contact Mingjiada for a quick evaluation and cash-out:
1. ADI (Analog Devices) and Maxim
ADI is the undisputed leader in this field, and its product line has expanded further following its acquisition of Maxim. Mingjiada consistently offers high prices for all models in the ADuM series of digital isolators. Whether you have dual-channel (e.g., ADUM1201) or quad-channel (e.g., ADUM1401) devices based on iCoupler technology, or models specifically designed for automotive applications, we are interested in purchasing them.
Key Acquisition Series: ADuM110N, ADuM120N, ADuM140D, ADuM240N, ADuM3160, ADuM4160 (Maxim’s original MAX series, such as the MAX14930, is also applicable).
2. Texas Instruments (TI)
As a global leader in analog chips, TI’s ISO series of digital isolators holds a significant market share and is widely used in demanding automotive and industrial environments. Mingjiada is particularly interested in the ISO77xx series, such as the ISO7741 and ISO7842. Due to their high reliability and low power consumption, these chips were a key focus for stockpiling during the chip shortage and currently have strong demand in the secondary market.
3. Silicon Labs and NVE
Silicon Labs has long been renowned for its isolation technology, with its isolator products striking a balance between low power consumption and high speed. Additionally, products from NVE Corporation—which specializes in magnetic isolation technology (such as the IL710 series)—are also among Mingjiada’s acquisition targets. As a professional recycler, Mingjiada possesses the capability to accurately assess the original value of these high-performance isolation chips.
4. Infineon and ON Semiconductor
With the upgrading of automotive electronic and electrical architectures, Infineon’s ISOFACE™ series of digital isolators and ON Semiconductor’s isolation driver chips designed for automotive functional safety are also key targets for Mingjiada’s inventory recycling. In particular, for integrated driver-and-isolator chips such as the TLE series, Mingjiada offers specialized cash purchase services.
5. High-Quality Domestic Brands
Mingjiada not only purchases top international brands but also focuses on high-quality inventory from domestic manufacturers amid the trend toward domestic substitution. As long as the models are compatible and the products are genuine, high-performance digital isolators from domestic manufacturers—including Naxinwei—are also included in our purchasing scope.
