HEXFET^® POWER MOSFET
IRFNG40
N-CHANNEL
1000 Volt, 3.5Ω HEXFET
HEXFET technology is the key to International
Rectifier’s advanced line of power MOSFET transis-
tors. The efficient geometry achieves very low on-
state resistance combined with high transconductance.
HEXFET transistors also feature all of the well-es-
tablish advantages of MOSFETs, such as voltage
control, very fast switching, ease of paralleling and
electrical parameter temperature stability. They are
well-suited for applications such as switching power
supplies, motor controls, inverters, choppers, audio
amplifiers, and high energy pulse circuits.
The Surface Mount Device (SMD-1) package repre-
sents another step in the continual evolution of sur-
face mount technology. The SMD-1 will give
designers the extra flexibility they need to increase
circuit board density. International Rectifier has en-
gineered the SMD-1 package to meet the specific
needs of the power market by increasing the size of
the termination pads, thereby enhancing thermal and
electrical performance.
