HEXFET® POWER MOSFET
IRFN140
N-CHANNEL
100 Volt, 0.077HEXFET
HEXFET technology is the key to International Rectifier’s
advanced line of power MOSFET transistors.The effi-
cient geometry achieves very low on-stateresistancecom-
bined with high transconductance.
HEXFET transistors also feature all of the well-establish
advantages of MOSFETs, such as voltage control, very
fast switching, ease of paralleling and electrical param-
eter temperature stability. They are well-suited for appli-
cations such as switching power supplies, motor controls,
inverters, choppers, audio amplifiers, and high energy
pulse circuits.
The Surface Mount Device (SMD-1) package represents
another step in the continual evolution of surface mount
technology. The SMD-1 will give designers the extra flex-
ibility they need to increase circuit board density. Inter-
national Rectifier has engineered the SMD-1 package to
meet the specific needs of the power market by increas-
ing the size of the termination pads, thereby enhancing
thermal and electrical performance.
