IRFR234B / IRFU234B
250V 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 converter and
switch mode power supplies.
