N-Channel UniFET TM MOSFET
5 00 V, 15 A, 380 mΩ
Features
? Low gate charge Q g results in simple drive requirement
(Typ. 33 nC)
? Improved Gate, avalanche and high reapplied dv/dt
ruggedness
? Reduced R DS(on) ( 330m? ( Typ.) @ V GS = 10 V, I D = 7.5 A)
? Reduced Miller capacitance and low Input capacitance
(Typ. C rss = 16 pF)
? Improved switching speed with low EMI
? 175 o C rated junction temperature
Description
UniFET TM MOSFET is Fairchild Semiconductor’s high
voltage MOSFET family based on planar stripe and
DMOS technology. This MOSFET is tailored to reduce
on-state resistance, and to provide better switching
performance and higher avalanche energy strength. This
device family is suitable for switching power converter
applications such as power factor correction (PFC), flat
panel display (FPD) TV power, ATX and electronic lamp
ballasts.
Applications
? Lighting
? Uninterruptible Power Supply
? AC-DC Power Supply
