In electronic circuit design, the selection of MOSFETs is crucial, especially in high-power applications such as DC-AC inverter power supplies, where the performance of the device directly determines the stability and efficiency of the system. Today, we will recommend a high-quality domestic MOSFET from Feihong Semiconductor—the 630A. Not only can it perfectly replace the IRF630, but its high reliability and excellent performance make it an ideal choice for DC-AC inverter power supply design. ### Feihong Semiconductor 630A: The Perfect Combination of Performance and Cost Efficiency The Feihong Semiconductor 630A is an N-channel enhancement mode field-effect transistor, suitable for the front-end DC-DC boost circuits of inverters with 48V/60V input. Its maximum drain-to-source DC voltage (VDS) can reach up to 200V, with a continuous drain current (ID) of 9A at 25°C, and it can still stably output 5.7A even at 100°C high temperatures. Additionally, its static on-resistance (RDS(ON)) is as low as 0.3~0.4Ω, effectively reducing power loss and improving system efficiency. In terms of dynamic characteristics, the 630A has an input capacitance (Ciss) of 420pF, output capacitance (Coss) of 99pF, and reverse transfer capacitance (Crss) of only 24pF. These parameters make it perform excellently in high-frequency switching applications, particularly meeting the design requirements of DC-AC inverter power supplies. Moreover, the 630A also features high dv/dt tolerance capability and 100% avalanche test certification, ensuring its reliability under harsh working conditions. ### Application of 630A in DC-AC Inverter Power Supplies DC-AC inverter power supplies are key equipment that convert direct current (DC) into alternating current (AC), widely used in solar power generation, uninterruptible power supply (UPS), and other fields. In this application, MOSFETs need to work stably under high voltage and large current conditions while having strict requirements for switching speed and power consumption. The Feihong Semiconductor 630A, with its low on-resistance and fast switching characteristics, can significantly reduce switching losses and improve the overall efficiency of the inverter. For example, in a 48V input DC-AC inverter power supply, the 630A can serve as the core component of the front-end DC-DC boost circuit. Its excellent dynamic characteristics and heat dissipation performance can effectively address thermal management challenges under high power density. Additionally, the 630A comes in various package forms, including TO-252 (FHD630A), TO-220 (FHP630A), and TO-220F (FHF630A), providing designers with flexible layout options. ### Why Choose Feihong Semiconductor 630A? 1. **Outstanding Performance**: The 630A excels in critical parameters such as voltage, current, and switching speed, meeting the high-performance demands of DC-AC inverter power supplies. 2. **High Reliability**: With 100% avalanche testing and high dv/dt tolerance, the 630A remains stable and reliable under harsh environmental conditions. 3. **Cost-Effective**: As a domestic MOSFET, the 630A offers competitive pricing while maintaining performance, helping enterprises reduce costs. 4. **Stable Supply**: As a major domestic production base for high-power MOSFETs, Feihong Semiconductor provides stable supply cycles and timely technical support. ### Limited-Time Offer: Free Samples!
