In the design of electronic circuits, the selection of MOSFETs is a crucial step. Especially in high-power applications, such as the front-end circuit of a 300W inverter, choosing the appropriate MOSFET not only affects the performance of the circuit but also directly impacts the product's reliability and cost control. As one of the key packaging bases for domestic high-power MOSFETs, Feihong Semiconductor has launched SGTMOSFET FHP3205D. With its excellent performance and cost-effectiveness, it has become an ideal replacement model for IRF3205 and is widely favored by the industry. ### Product Features and Advantages of FHP3205D FHP3205D is an N-channel MOSFET developed by Feihong Semiconductor based on planar process technology, specifically designed for high-power applications. Its main parameters include: - **High Voltage and Current Capability**: Maximum drain-to-source DC voltage (VDS) is 55V, continuous drain current (ID) at 25°C can reach up to 110A, meeting the high-power demands of a 300W inverter. - **Low On-State Resistance**: Static on-state resistance (RDS(on)) is only 7.6mΩ (typical value), effectively reducing conduction losses and improving circuit efficiency. - **Fast Switching Characteristics**: Turn-on delay time (td(on)) is 19.9ns, rise time (tr) is 83ns, ensuring stable operation in high-frequency switching scenarios. - **High Reliability**: High avalanche energy tolerance, single-pulse avalanche energy (EAS) is 312.5mJ, suitable for harsh working environments. ### Application of FHP3205D in the Front-End Circuit of a 300W Inverter The front-end circuit of a 300W inverter has extremely high requirements for MOSFETs, demanding devices with high voltage, large current, low on-state resistance, and fast switching capabilities. FHP3205D perfectly meets these application scenarios with its excellent electrical characteristics. In actual case studies, when an inverter manufacturer upgraded their products, they chose FHP3205D to replace the original IRF3205. Comparative tests showed that FHP3205D significantly improved conduction loss and switching efficiency, while its consistency and reliability received high recognition from customers. Additionally, Feihong Semiconductor’s technical support and comprehensive supply system helped clients shorten their R&D cycles and reduce production costs. ### Solving User Selection Pain Points For factory procurement and supply chain personnel, the selection of MOSFETs often faces the following pain points: 1. **Complex Parameters**: The detailed parameter manual and reference designs for FHP3205D help users quickly complete the selection. 2. **Counterfeit Risk**: Feihong Semiconductor provides genuine original products, ensuring product quality. 3. **Heat Dissipation Design**: FHP3205D’s low thermal resistance design effectively reduces heat dissipation pressure. 4. **Stable Supply**: Feihong Semiconductor has a mature supply system, supporting urgent orders and long-term inventory. ### Limited-Time Discount, Free Sample To allow more users to understand the excellent performance of FHP3205D, Feihong Semiconductor has specially launched a limited-time discount promotion and provides free sample services.
