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.

FQPF5N40 N-Channel QFET MOSFET November 2013 FQPF5N40 N-Channel QFET MOSFET 400 V, 3.0 A, 1.6 Description Features This N-Channel enhancement mode power MOSFET is 3.0 A, 400 V, R = 1.6 (Max.) V = 10 V, DS(on) GS produced using Fairchild Semiconductors proprietary I = 1.5 A D planar stripe and DMOS technology. This advanced Low Gate Charge (Typ. 10 nC) MOSFET technology has been especially tailored to reduce on-state resistance, and to provide superior switching Low Crss (Typ. 7 pF) performance and high avalanche energy strength. These 100% Avalanche Tested devices are suitable for switched mode power supplies, active power factor correction (PFC), and electronic lamp ballasts.
