IRF640
The IRF640 is a 200 V, 18 A N-channel power MOSFET from STMicroelectronics, designed for high-speed switching in power electronics. With low on-resistance and efficient conduction, it provides reliable performance in circuits where heat management and current handling are critical.
This MOSFET is suitable for UPS systems, DC-DC converters, inverters, and motor control circuits. Its avalanche-rugged construction allows tolerance to high pulse energies, making it appropriate for industrial automation, telecommunications, and renewable energy systems.
Encased in a TO-220 package, the IRF640 supports easy mounting and effective thermal management. Its low gate threshold voltage and fast switching capabilities reduce power loss in high-frequency designs. Its durability, voltage tolerance, and efficient operation make it suitable for energy-conscious applications in automotive, lighting, and industrial control systems.
