Description
UniFETTM 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. The body diode’s reverse recovery performance
of UniFET FRFET® MOSFET has been enhanced by lifetime
control. Its trr is less than 100nsec and the reverse dv/dt
immunity is 15V/ns while normal planar MOSFETs have over
200nsec and 4.5V/nsec respectively. Therefore, it can remove
additional component and improve system reliability in certain
applications in which the performance of MOSFET’s body diode
is significant. 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.
