Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers
will need to change in order to meet ON Semiconductor’s system requirements. Since the ON Semiconductor
product management systems do not have the ability to manage part nomenclature that utilizes an underscore
(_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain
device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated
device numbers. The most current and up-to-date ordering information can be found at
www.onsemi.com.

email any questions regarding the system integration to

II MOSFET
Description
UniFET
TM
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. This device family is suitable for switching power con-
verter applications such as power factor correction (PFC), flat
panel display (FPD) TV power, ATX and electronic lamp bal-
lasts.
Applications
• LCD/ LED TV
• Lighting
• Uninterruptible Power Supply
• AC-DC Power Supply
