Descriptions
Descriptions of onsemi IRFS634B provided by its distributors.
Trans MOSFET N-CH 250V 8.1A 3-Pin(3+Tab) TO-220F
250V N-CHANNEL MOSFET Power Field-Effect Transistor, 8.1A I(D), 250V, 0.45ohm, 1-Element, N-Channel, Silicon, Metal-oxide Semiconductor FET
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 and switch mode power supplies.
