The power semiconductor industry experienced a structural recovery at the beginning of 2026, yet the MOSFET sector is caught in a dual dilemma of "shortage + price increases." Major brands like CR Micro and Huayi Micro have raised their prices, with typical increases starting at 10%, and some part numbers seeing hikes exceeding 20%. Simultaneously, tight capacity has led to significantly extended lead times. Downstream manufacturing enterprises are facing the predicament of "unable to buy, unable to afford," causing disruptions to production plans and mounting cost pressures.

Under the combined effects of the industry cycle, rising costs, and surging demand, the supply-demand imbalance in the MOSFET market is difficult to alleviate in the short term. Soaring prices of precious metals like copper and silver, continuously increasing costs for 8-inch wafer foundry, coupled with explosive demand from sectors like AI servers, new energy vehicles, and photovoltaic energy storage, have kept leading manufacturers' capacity under tight constraints. For enterprises reliant on these brands, finding alternative models that match performance, offer stable supply, and provide excellent cost-effectiveness has become the key to breaking the deadlock.

At this critical moment, leveraging its Fab-Lite IDM model and robust supply chain system, Xinmai Semiconductor has introduced the SDN04N0P9CN, a 40V N-channel SGT MOSFET. It precisely matches the specifications of equivalent models from CR Micro and Huayi Micro. With its core advantages of "no compromise on performance, guaranteed supply, and better cost control," it has emerged as the optimal alternative solution for downstream enterprises.

This product adopts advanced SGT (Shielded Gate Trench) technology, featuring a Vds voltage of 40V, an Id current of approximately 40A (at 10V drive), and a low Rds(on) of 0.9mΩ@10V. Packaged in PDFN5×6 (DFN-8), it is perfectly compatible with popular models like Huayi Micro's V009N04 and CR Micro's HGQ024N04A. It requires no PCB design modifications, enabling direct drop-in replacement, which significantly reduces substitution costs and adaptation risks.

Compared to the shortage-plagued, price-hiked models from CR Micro and Huayi, the core advantages of the SDN04N0P9CN lie in "stable supply + high cost-effectiveness." Relying on its dual domestic and international supply chain system, Xinmai mitigates single-supply-chain risks, enabling stable bulk supply with controllable lead times. This fundamentally addresses the pain points of "difficulty in sourcing and long waiting periods." Meanwhile, thanks to proprietary processes and efficient cost control, the product maintains reasonable pricing against the backdrop of industry-wide price increases, highlighting its cost-effectiveness and effectively helping enterprises reduce procurement costs.

As a National High-Tech Enterprise and a specialized, sophisticated, and innovative SME in Zhejiang Province, Xinmai boasts a core R&D team with over 20 years of experience. The company has built a comprehensive product portfolio of silicon-based and silicon carbide-based power devices. Its products are widely used in motor drives, battery management, communication base stations, as well as in high-end fields like automotive, data centers, and AI servers. Having passed multiple certifications including ISO9001, Xinmai's products undergo rigorous reliability testing. Their stability and durability are comparable to top brands, making them perfectly suitable for various medium and low-voltage power application scenarios.

Currently, the import substitution of semiconductors has entered a critical stage. As a backbone force in domestic power semiconductors, Xinmai focuses on "innovation-driven, independent, and controllable" development, deepening its expertise in the power device field to break foreign monopolies and domestic supply bottlenecks from leading brands. The launch of the SDN04N0P9CN is not only a testament to Xinmai's technical strength but also a significant measure to help downstream enterprises overcome difficulties, reduce costs, and enhance efficiency.

No more waiting amidst shortages. No more enduring the pressure of price hikes. When CR Micro and Huayi models are scarce and prices are high, Xinmai's SDN04N0P9CN, with its core competitiveness of "precise substitution, stable supply, and high cost-effectiveness," provides a reliable solution for downstream manufacturing enterprises. It empowers businesses to calmly navigate market fluctuations, lower operational risks, and seize opportunities in the wave of the industry's structural recovery.

Choosing Xinmai's SDN04N0P9CN is not only choosing supply security and cost advantages but also choosing the opportunity to grow alongside the domestic semiconductor industry. In the future, Xinmai will continue to deepen its commitment to the power device field, launching more high-quality products to help downstream enterprises reduce costs and increase efficiency, driving the high-quality development of China's power semiconductor industry.
