Mingjiada Electronics has been deeply involved in the electronic component distribution sector for many years, dedicated to providing customers with high-quality, cost-effective electronic component solutions. Leveraging our stable supply chain channels and robust stock inventory capabilities, we offer a wide range of genuine STMicroelectronics (ST) silicon carbide (SiC) Schottky diodes.
In an era of energy shortages and increasingly stringent energy efficiency requirements, Mingjiada has partnered with STMicroelectronics to bring you revolutionary wide bandgap (WBG) power devices—the STPSC series of silicon carbide (SiC) Schottky diodes—helping your products achieve a quantum leap in efficiency, power density, and reliability.
Why Choose ST SiC Schottky Diodes?
As a global leader in the power semiconductor industry, ST’s SiC diodes utilize unique wide-bandgap material technology. Compared to traditional silicon-based fast-recovery diodes, ST’s SiC Schottky diodes feature near-zero reverse recovery current and temperature-independent switching characteristics.
Key Technical Advantages:
Zero reverse recovery: Virtually no tailing current during turn-off, significantly reducing switching losses and markedly improving PFC efficiency in hard-switching topologies.
High-frequency capability: Reduced ringing and electromagnetic interference (EMI), allowing for smaller magnetic components and filters, thereby reducing system size and cost.
High Temperature Resistance and Reliability: Operates at junction temperatures up to +175°C and features extremely high forward surge withstand capability, ensuring long-term stable operation in harsh environments.
Automotive-Grade Certification: Multiple models are AEC-Q101 certified and support PPAP, perfectly meeting the high-reliability requirements of applications such as electric vehicles (EVs) and on-board chargers (OBCs).

Applications: From industrial to automotive, covering high-power applications
ST’s silicon carbide (SiC) Schottky diodes are specifically designed for high-efficiency, high-power-density hard-switching topologies and deliver outstanding performance in the following areas:
1. Electric Vehicles and On-Board Chargers
With the widespread adoption of 800V high-voltage platforms, ST’s 1200V SiC diodes (such as the STPSC20H12G2) have become critical components. Primarily used in the PFC stage and high-voltage DC-DC converters of on-board chargers (OBCs), they significantly reduce charging losses, shorten charging times, and extend vehicle range.
2. Renewable Energy and Energy Storage
In photovoltaic inverters and energy storage converters, SiC diodes are used in boost circuits. Their low-loss characteristics directly translate to higher power conversion efficiency, maintaining high performance even in high-temperature environments, which helps reduce thermal management costs.
3. Server and Communication Power Supplies
The explosive growth in AI computing power demands has placed stringent requirements on the efficiency of server power supplies (PSUs) (e.g., the 80 PLUS Titanium standard). ST’s 650V SiC diodes (such as the STPSC8H065 series) are widely used in high-end server and telecommunications equipment power supplies for power factor correction, achieving extremely high energy efficiency metrics at a lower cost.
4. Industrial Infrastructure and Home Appliances
From industrial-grade motor drives to high-end variable-frequency home air conditioners, the use of SiC diodes helps suppress electromagnetic interference, enhance system durability, and meet increasingly stringent international energy efficiency regulations.
