Description
This new series of Low Charge HEXFET Power MOSFETs achieve significantly
lower gate charge over conventional MOSFETs. Utilizing advanced Hexfet
technology the device improvements allow for reduced gate drive requirements,
faster switching speeds and increased total system savings. These device
improvements combined with the proven ruggedness and reliability of HEXFETs
offer the designer a new standard in power transistors for switching applications.
The TO-247 package is preferred for commercial-industrial applications where
higher power levels preclude the use of TO-220 devices. The TO-247 is similar
but superior to the earlier TO-218 package because of its isolated mounting hole.
