Description
04N70BF-H series are specially designed as main switching devices for universal 90~265VAC off-line AC/DC converter applications. TO-220FM type provide high blocking voltage to overcome voltage surge and sag in the toughest power system with the best combination of fast switching,ruggedized design and cost-effectiveness.
The TO-220FM package is universally preferred for all commercialindustrial applications. The device is suited for switch mode power supplies ,DC-AC converters and high current high speed switching circuits.
An N-channel MOSFET (Metal Oxide Semiconductor Field Effect Transistor) is a type of field effect transistor (FET) that uses an N-type semiconductor material as the conducting channel to control the flow of current.
N-channel MOSFETs are widely used in a variety of electronic applications due to their high input impedance, fast switching speeds, and low power consumption. They are commonly used as switches, amplifiers, and voltage regulators.
