HEXFET® POWER MOSFET
200 Volt, 0.18Ω HEXFET
HEXFET technology is the key to International Rectifier’s advanced line of power MOSFET transistors. The efficient geometry achieves very low on-state 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.
