MOS FIELD EFFECT TRANSISTOR
2SK4035
SWITCHING
N-CHANNEL POWER MOSFET
DATA SHEET
Document No. D17447EJ1V0DS00 (1st edition)
Date Published July 2005 NS CP(K)
Printed in Japan
2005
DESCRIPTION
2SK4035 is the best switching element for the DC-DC
converter usage from 24 to 48 V in the direct current input
voltage. It excels in the switching characteristics in low on-state
resistance and because it is the small size surface mounting
externals, is the best for the high-speed switching usage of the
equipment that promotes the automation of space-saving and
mounting.
FEATURES
• Low input capacitance
C
iss = 74 pF TYP.
• Low on-state resistance
R
DS(on) = 4.5 MAX. (VGS = 10 V, ID = 0.25 A)
• Small and surface mount package (SC-96)

NEC Electronics products are classified into the following three quality grades: "Standard", "Special" and
"Specific".
The "Specific" quality grade applies only to NEC Electronics products developed based on a customer-
designated "quality assurance program" for a specific application. The recommended applications of an NEC
Electronics product depend on its quality grade, as indicated below. Customers must check the quality grade of
each NEC Electronics product before using it in a particular application.
"Standard": Computers, office equipment, communications equipment, test and measurement equipment, audio
and visual equipment, home electronic appliances, machine tools, personal electronic equipment
and industrial robots.
"Special": Transportation equipment (automobiles, trains, ships, etc.), traffic control systems, anti-disaster
systems, anti-crime systems, safety equipment and medical equipment (not specifically designed
for life support).
"Specific": Aircraft, aerospace equipment, submersible repeaters, nuclear reactor control systems, life
support systems and medical equipment for life support, etc.
The quality grade of NEC Electronics products is "Standard" unless otherwise expressly specified in NEC
Electronics data sheets or data books, etc. If customers wish to use NEC Electronics products in applications
not intended by NEC Electronics, they must contact an NEC Electronics sales representative in advance to
determine NEC Electronics' willingness to support a given application.
