l 175°C Operating Temperature
l Fast Switching
l Ease of Paralleling
l Simple Drive Requirements
Description
Third Generation HEXFETs from International Rectifier provide the designer with
the best combination of fast switching, ruggedized device, low on-resistance and
cost-effectiveness.
The HEXSense device provides an accurate fraction of the drain current through
the additional two leads to be used for control or protection of the device. These
devices exhibit similar electrical and thermal characteristics as their IRF-series
equivalent part numbers. The provision of a kelvin source connection effectively
eliminates problems of common source inductance when the HEXSence is
used as a fast, high-current switch in non current-sensing applications.
