Today, as the carbon neutrality goal drives the global energy transition, silicon carbide (SiC) power devices, with their disruptive efficiency and power density advantages, are becoming the core engines in the fields of new energy, industrial power supplies, and electric vehicles. As a leading enterprise deeply engaged in the electronic component supply chain for two decades, Shenzhen Mingjiada Electronics Co., Ltd. focuses on cutting-edge power semiconductor technology and has taken the lead in building a one-stop supply system covering the full range of Wolfspeed discrete silicon carbide Schottky diodes, providing efficient and reliable electronic "blood vessels" for thousands of industries.
I. Technological Innovation: The Core Advantages of Wolfspeed SiC Schottky Diodes
Wolfspeed (formerly Cree), as the global pioneer of silicon carbide technology, its discrete Schottky diodes adopt a unique MPS (Merged PiN Schottky) structure design, demonstrating revolutionary performance in high-temperature and high-frequency scenarios:
Zero reverse recovery charge (Qrr=0) : Completely eliminates the energy loss of traditional silicon-based diodes during the switching process, significantly improving system efficiency (especially in PFC circuits, the efficiency increase can reach over 5%), while reducing electromagnetic interference (EMI).
Stable operation at 175°C high temperature: The junction temperature tolerance far exceeds the 150°C limit of silicon devices, making it suitable for high-temperature sealed environments (such as on-board charging compartments and industrial motor drivers) without the need for additional cooling systems.
Positive temperature coefficient feature: Supports multi-chip parallel current sharing, avoiding the risk of thermal runaway, and can be easily expanded to high-power applications.
Full voltage coverage: Mingjiada has products in stock for all voltage ranges of 650V, 1200V and 1700V, such as:
650V series (such as CSD01060) : Suitable for server power supplies and consumer-grade fast charging, supporting 4A-60A current;
1700V high-voltage series (such as C6D10170H) : Specifically designed for electric vehicle ultra-fast charging piles and photovoltaic inverters, with current specifications ranging from 10A to 25A, it meets the requirements of megawatt-level systems.
Ii. Application Scenarios: The core driving force from new energy to intelligent vehicles
With the triple characteristics of "high frequency + high efficiency + high reliability", Wolfspeed SiC Schottky diodes are reshaping the power architecture of key industries:
New energy vehicles: As the core rectifier device for on-board chargers (OBC) and DC-DC converters, it helps 800V high-voltage platforms achieve a conversion efficiency of over 98%, while reducing weight by 30% (compliant with AEC-Q101 automotive standard certification).
Green energy system: Replacing silicon diodes in photovoltaic inverters, increasing the switching frequency to over 100kHz, reducing the volume of inductors/capacitors by 50%, and driving the system power density to exceed 50W/in³.
Industrial power supplies and data centers: PFC circuits used in telecommunications power supplies and server PSU reduce full-load losses by 40%, saving over 10,000 yuan in electricity costs annually (based on a 10kW power supply).
Energy storage and emergency power: Provide millisecond-level response and zero recovery loss for UPS and battery management systems (BMS), ensuring 99.99% availability of grid-level energy storage systems.
Iii. Mingjiada One-Stop Supply: Full-chain Empowerment from chips to services
Choosing Mingjiada Electronics as the partner of Wolfspeed SiC Schottky diodes means obtaining dual engine support of "technology + supply chain" that goes beyond traditional distribution:
Genuine product guarantee and massive inventory
All Wolfspeed devices are sourced from the original factory and authorized channels, eliminating the risks of refurbishment and counterfeiting.
Our dual warehousing centers in Shenzhen and Hong Kong always keep a full range of CSD, C6D and other products in stock, supporting same-day order placement and next-day delivery with an extremely fast response.
Flexible procurement and full life cycle services
Support sample applications with a minimum order of one piece to meet the requirements of R&D verification.
Offer bulk stepped quotations (with a price reduction of up to 15% for orders of thousands of pieces) to lower the cost of large-scale mass production.
We also offer inventory recovery services: For unused Wolfspeed diodes (such as industrial scraps and remaining inventory from projects), our professional team will assess them and repurchase them at 50-75% of the new product price in cash to alleviate the occupation of funds.
Global logistics and resilient supply chains
Relying on the DHL/UPS international logistics network, we achieve global delivery within 72 hours.
Dynamically monitor out-of-stock models (such as high-demand model C6D10170H), and ensure supply continuity through pre-stockpiling and recommending alternative models.
Mingjiada Electronics, with its core competitiveness in original factory resources, technological accumulation and agile services, continuously deepens its strategic cooperation with Wolfspeed, and is committed to maximizing the value of each SiC chip in the customer's system.
