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

FQU3N50C
N-Channel QFET® MOSFET
500 V, 2.5 A, 2.5 Ω
Description
Features
This N-Channel enhancement mode power MOSFET is produced
using Fairchild Semiconductor’s proprietary planar stripe and
DMOS technology. This advanced MOSFET technology has
been especially tailored to reduce on-state resistance, and to
provide superior switching performance and high avalanche
energy strength. These devices are suitable for switched mode
power supplies, active power factor correction (PFC), and
electronic lamp ballasts.
• 2.5 A, 500 V, RDS(on) = 2.5 Ω (Max.) @ VGS = 10 V, ID = 1.25 A
• Low Gate Charge (Typ. 10 nC)
• Low Crss (Typ. 8.5 pF)
• 100% Avalanche Tested

LIFE SUPPORT POLICY
FAIRCHILD’S PRODUCTS ARE NOT AUTHORIZED FOR USE AS CRITICAL COMPONENTS IN LIFE SUPPORT DEVICES OR SYSTEMS WITHOUT THE
EXPRESS WRITTEN APPROVAL OF FAIRCHILD SEMICONDUCTOR CORPORATION.
As used here in:
1. Life support devices or systems are devices or systems which, (a) are
intended for surgical implant into the body or (b) support or sustain life,
and (c) whose failure to perform when properly used in accordance with
instructions for use provided in the labeling, can be reasonably
expected to result in a significant injury of the user.
2.
A critical component in any component of a life support, device, or
system whose failure to perform can be reasonably expected to cause
the failure of the life support device or system, or to affect its safety or
effectiveness.
ANTI-COUNTERFEITING POLICY
Fairchild Semiconductor Corporation’s Anti-Counterfeiting Policy. Fairchild’s Anti-Counterfeiting Policy is also stated on our external website,
www.Fairchildsemi.com, under Sales Support.
Counterfeiting of semiconductor parts is a growing problem in the industry. All manufactures of semiconductor products are experiencing counterfeiting of their
parts. Customers who inadvertently purchase counterfeit parts experience many problems such as loss of brand reputation, substandard performance, failed
application, and increased cost of production and manufacturing delays. Fairchild is taking strong measures to protect ourselves and our customers from the
proliferation of counterfeit parts. Fairchild strongly encourages customers to purchase Fairchild parts either directly from Fairchild or from Authorized Fairchild
Distributors who are listed by country on our web page cited above. Products customers buy either from Fairchild directly or from Authorized Fairchild
Distributors are genuine parts, have full traceability, meet Fairchild’s quality standards for handing and storage and provide access to Fairchild’s full range of
up-to-date technical and product information. Fairchild and our Authorized Distributors will stand behind all warranties and will appropriately address and
warranty issues that may arise. Fairchild will not provide any warranty coverage or other assistance for parts bought from Unauthorized Sources. Fairchild is
committed to combat this global problem and encourage our customers to do their part in stopping this practice by buying direct or from authorized distributors.
