The HEXFET® technology is the key to International
Rectifier’s HiRel 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 trans conductance.
The HEXFET transistors also feature all of the well
established advantages of MOSFETs such as voltage
control, very fast switching 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.
