IRF640B/IRFS640B
200V N-Channel MOSFET
General Description
These N-Channel enhancement mode power field effect
transistors are produced using Fairchild’s proprietary, planar, DMOS technology.
This advanced technology has been especially tailored to minimize on-state resistance, provide superior switching performance, and withstand high energy pulse in the avalanche and commutation mode.
These devices are well suited for high efficiency switching DC/DC converters, switch mode power supplies, DC-AC converters for uninterrupted power supply and motor control.
