Product Summary
HEXFET technology is the key to International
Rectifier’s advanced line of power MOSFET transistors. The efficient geometry achieves very low onstate resistance combined 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 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 represents another step in the continual evolution of surface mount technology. The SMD-1 will give
designers the extra flexibility they need to increase
circuit board density. International Rectifier has engineered 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.
