The HEXFET®technology is the key to International
Rectifier’s advanced line of power MOSFET transistors.
The efficient geometry and unique processing of this
latest “State of the Art” design achieves: very low on-
state resistance combined with high transconductance.
The HEXFET transistors also feature all of the well
established advantages of MOSFETs such as voltage
control, very fast switching, ease of parelleling and
temperature stability of the electrical parameters.
They are well suited for applications such as switching
power supplies, motor controls, inverters, choppers, audio
amplifiers and high energy pulse circuits.
