In the design of electronic circuits, the selection of MOSFETs is often a major challenge for engineers. Especially in the field of switch-mode power supplies, the performance of the MOSFET directly affects the efficiency, stability, and lifespan of the power supply. Faced with the plethora of products on the market, how to select a MOSFET that meets performance requirements while also being cost-effective? The 50N06B MOSFET introduced by Fei Hong Semiconductor might just be the answer you've been looking for. ### **Key Points for MOSFET Selection in Switching Power Supplies** As an indispensable component in modern electronic equipment, switching power supplies have very stringent requirements for MOSFETs. When selecting, engineers usually focus on the following key parameters: 1. **On-resistance (Rds(on))**: A lower on-resistance can significantly reduce power loss and improve power supply efficiency. The Rds(on) of the Fei Hong 50N06B is only 8.5mΩ~10.5mΩ, making it highly suitable for high current applications. 2. **Switching speed**: Fast switching capability can reduce switching losses and enhance the dynamic response of the power supply. The 50N06B has fast switching speed with a turn-on delay time (td(on)) of only 16ns and rise time (tr) of 10ns. 3. **Thermal performance**: High temperature is one of the main causes of MOSFET failure. The Fei Hong 50N06B uses trench process design with low internal resistance and low temperature rise, effectively extending the life of the device. 4. **Reliability**: 100% avalanche tested, thermal resistance tested, and Rg tested, ensuring stable operation under high load conditions. ### **Fei Hong 50N06B: An Ideal Choice for Domestic Substitution** In the design of switching power supplies, the Fei Hong 50N06B not only fully complies with international brands such as IRFZ44N, STP60NF06 but is also a domestic alternative model for FQP50N06. Its advantages lie in: - **Excellent performance**: Maximum drain-to-source DC voltage (VDS) of 60V, continuous drain current (ID) of up to 75A, meeting the design needs of most switching power supplies. - **High cost-effectiveness**: As a domestic MOSFET, the Fei Hong 50N06B is more competitive in price while its performance is comparable to international brands. - **Stable supply**: Located in the Guangzhou Bonded Area, Fei Hong Semiconductor has complete production lines and supply chains, ensuring short delivery cycles and support for urgent orders. ### **Time-Limited Promotion, Supporting Your Design** To help more engineers experience the excellent performance of the Fei Hong 50N06B, Fei Hong Semiconductor is specially launching a time-limited promotion!
