FQNL2N50B N-Channel QFET
®
MOSFET
This N-Channel enhancement mode power MOSFET is
produced using Fairchild Semiconductor’s proprietary planar
stripe and DMOS technology. This advanced MOSFET
technology has been especially tailored to reduce on-state
resistance, and to provide superior switching performance
and high avalanche energy strength. These devices are
suitable for switched mode power supplies, active power
factor correction (PFC), and electronic lamp ballasts.
