The Logic Level ‘L’ series of power MOSFETs are designed to be operated with level logic gate-to-source
voltage of 5V. In addition to the well established

characterstics of HEXFETs , they have the added advantage of providing low drive requirements to interface power loads to logic level IC’s and microprocessors.
Fields of applications include: high speed power applications such as switching regulators, switching converters, motor drivers, solenoid and relay drivers and
drivers for high power bipolar switching transistors requiring high speed and low gatedrive voltage.
The HEXFET technology is the key to International
Rectifier’s advanced line of logic level power MOSFET
transistors. The efficient geometry and unique processing of the HEXFET achieve very low on-state resistance
combined with high transconductance and great device ruggedness.
