IRFW640B / IRFI640B
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.
Features
18A, 200V, RDS(on) = 0.18Ω @VGS = 10 V Low gate charge ( typical 45 nC) Low Crss ( typical 45 pF) Fast switching 100% avalanche tested Improved dv/dt capability
