Description
UniFETTM II MOSFET is Fairchild Semiconductor’s high voltage
MOSFET family based on advanced planar stripe and DMOS
technology. This advanced MOSFET family has the smallest
on-state resistance among the planar MOSFET, and also pro-
vides superior switching performance and higher avalanche
energy strength. In addition, internal gate-source ESD diode
allows UniFET II MOSFET to withstand over 2kV HBM surge
stress. The body diode’s reverse recovery performance of
UniFET II FRFET® MOSFET has been enhanced by lifetime
control. Its trr is less than 100nsec and the reverse dv/dt immu-
nity 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 bal-
lasts.
