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. Please
email any questions regarding the system integration to Fairchild_questions@onsemi.com.

N-Channel QFET® MOSFET
400 V, 30 A, 140 mΩ
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.
• 30 A, 400 V, RDS(on) = 140 mΩ (Max.) @ VGS = 10 V,
ID = 15 A
• Low Gate Charge (Typ. 90 nC)
• Low Crss ( Typ. 60 pF)
• 100% Avalanche Tested

Datasheet Identification Product Status Definition
Advance Information Formative / In Design Datasheet contains the design specifications for product development. Specifications
may change in any manner without notice.
Preliminary First Production
Datasheet contains preliminary data; supplementary data will be published at a later
date. Fairchild Semiconductor reserves the right to make changes at any time without
notice to improve design.
No Identification Needed Full Production Datasheet contains final specifications. Fairchild Semiconductor reserves the right to
make changes at any time without notice to improve the design.
Obsolete Not In Production Datasheet contains specifications on a product that is discontinued by Fairchild
Semiconductor. The datasheet is for reference information only.
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.
