The FHF10N65B is a 650V 10A 50W 900mO@10V,5A N Channel TO-220F-3 MOSFET manufactured by FeiHong. This device is a Metal-Oxide-Semiconductor Field-Effect Transistor (MOSFET) designed for high-current switching applications, offering superior reliability and performance. It is a three-terminal device with a source, gate, and drain terminal. The 650V rating makes it suitable for applications requiring a higher voltage and the 10A current rating indicates it can handle higher current applications. The 900mO@10V, 5A rating indicates the device has low on-state resistance to effectively handle higher current in on state. The 50W rating indicates its power dissipation. The device is also RoHS compliant, making it environmentally friendly.
