IRF830B/IRFS830B

500V N-Channel MOSFET

IRF830B/IRFS830B

November 2001

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

Features

• 4.5A, 500V, R

• Low gate charge ( typical 27 nC)

• Low Crss ( typical 17 pF)

• Fast switching

• 100% avalanche tested

• Improved dv/dt capability

= 1.5Ω @VGS = 10 V

suited for high efficiency switch mode power supplies,
power factor correction and electronic lamp ballasts based
on half bridge.
