Fairchild FQU4N25 N-channel qfet mosfet Datasheet

FQD4N25 / FQU4N25
N-Channel QFET MOSFET
250 V, 3 A, 1.75Ω
Description
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.
Features
• 3 A, 250 V, RDS(on) = 1.75 Ω (Max) @VGS = 10 V,
ID = 1.5 A
• Low Gate Charge (Typ. 4.3 nC)
• Low Crss (Typ. 4.8 pF)
• 100% Avalanche Tested

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.

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.
