HEXFET technology is the key to International Rectifier’s

advanced line of power MOSFET transistors.The effi-

cient geometry achieves very low on-stateresistancecom-

binedwithhightransconductance.

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.
