Is Now Part of To learn more about ON Semiconductor, please visit our website at www.onsemi.com 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 Semiconductors 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. Please email any questions regarding the system integration to Fairchild questions onsemi.com.

V = 10 V, I = 5 A UniFET MOSFET is Fairchild Semiconductors high voltage DS(on) GS D MOSFET family based on planar stripe and DMOS technology. Low Gate Charge (Typ. 21 nC) This MOSFET is tailored to reduce on-state resistance, and to Low C (Typ. 11 pF) provide better switching performance and higher avalanche rss TM energy strength. UniFET Ultra FRFET MOSFET has much 100% Avalanche Tested superior body diode reverse recovery performance. Its trr is less Improved dv/dt Capability than 50nsec and the reverse dv/dt immunity is 20V/nsec while normal planar MOSFETs have over 200nsec and 4.5V/nsec RoHS Compliant respectively. Therefore UniFET Ultra FRFET MOSFET can remove additional component and improve system reliability in Applications certain applications that require performance improvement of the LCD/LED/PDP TV MOSFETs body diode. This device family is suitable for switching power converter applications such as power factor Lighting correction (PFC), flat panel display (FPD) TV power, ATX and Uninterruptible Power Supply electronic lamp ballasts.
