In recent years, with the rapid development of the new energy industry, energy storage power supplies, as one of the core components, have seen an increasing demand for high-performance semiconductor devices. Against this backdrop, domestic SGT MOSFETs have gradually come to the fore and become a focal point for engineers. Today, we are pleased to invite Li Gong, a technical expert from Feihong Semiconductor, to share with us a highly anticipated product—the 170N8F3A—and its application value in the field of energy storage power supplies. **Reporter:** Li Gong, could you briefly introduce the 170N8F3A product? **Li Gong:** Of course. The 170N8F3A is an N-channel enhancement-mode field-effect transistor using SGT technology, featuring extremely low RDSON on-resistance and excellent short-circuit resistance performance. Its package types include TO-220, TO-263, and TO-3PN, meeting the needs of different application scenarios. Moreover, this product performs excellently in key parameters such as voltage, current, and switching speed, making it particularly suitable for high-frequency switching and high-current applications. **Reporter:** What unique advantages does the 170N8F3A have in the field of energy storage power supplies? **Li Gong:** Energy storage power supplies have very high requirements for the performance of semiconductor devices, especially in terms of efficiency, heat dissipation, and reliability. The RDSON of the 170N8F3A is as low as 2.95~4mΩ, significantly reducing conduction losses and improving system efficiency. At the same time, its switching speed is fast, with an opening delay time of only 41ns, making it very suitable for push-pull or half-bridge and full-bridge designs in DC-DC boost structures. Additionally, the 170N8F3A has passed 100% avalanche testing and thermal resistance testing, ensuring stable operation in high-temperature, high-power environments. **Reporter:** I heard that the 170N8F3A can replace some international brand products. Could you explain in detail? **Li Gong:** Yes, the 170N8F3A can perfectly replace international brand products such as STP170N8F7 and IPP037N08N3G. In terms of performance parameters, the 170N8F3A not only matches them but even has certain advantages in some aspects. For example, its total gate charge (Qg) is only 124nC, which is lower than some competitors, meaning lower driving losses and higher switching efficiency. For engineers, choosing the 170N8F3A not only reduces costs but also avoids production stagnation caused by shortages. **Reporter:** What are the advantages of Feihong Semiconductor in terms of technology research and development and production? **Li Gong:** Feihong Semiconductor is one of the key packaging bases for domestic high-power MOSFETs, with a modern factory covering 20 mu and a production workshop area of 13,000 square meters. We adopt advanced SGT technology and strict testing processes to ensure that every product meets RoHS standards. Additionally, we provide comprehensive technical support, including data sheets, reference designs, and failure analysis, to help customers quickly implement product applications. **Reporter:** Do you have any suggestions for engineers who are currently selecting products? **Li Gong:** When selecting products, engineers need to comprehensively consider parameter matching, heat dissipation design, and cost control based on specific application scenarios. The 170N8F3A, with its excellent performance and reliability, has become a preferred solution in the field of energy storage power supplies.
