FQD7N20L / FQU7N20L

FQD7N20L / FQU7N20 L

200V LOGIC N-Channel MOSFET

General Description

These N-Channel enhancement mode power field effect

transistors are produced using Fairchild’s proprietary,

planar stripe, DMOS technology.

This advanced technology is especially tailored to minimize

on-state resistance, provide superior switching

performance, and withstand high energy pulse in the

avalanche and commutation modes. These devices are

well suited for high efficiency switching DC/DC conv ert ers,

switch mode power supplies, and motor control.

Features

• 5.5A, 200V, RDS(on) = 0.75Ω @VGS = 10 V

• Low gate charge ( typical 6.8 nC)

• Low Crss ( typical 8.5 pF)

• Fast switching

• 100% avalanche tested

• Improved dv/dt capability

• Low level gate drive requirement allowing direct

operation from logic drivers

ANTI-COUNTERFEITING POLICY

Fairchild Semiconductor Corporation’s Anti-Counterfeiting Policy. Farichild’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. Farichild strongly encourages customers to purchase Farichild 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 Farichild’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. Farichild 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.
