General Description
This N-Channel MOSFET is produced using Fairchild
Semiconductor’s
Advancements in both silicon and Dual Cool
technologies have been combined to offer the lowest r
while maintaining excellent switching performance by extremely
low Junction-to-Ambient thermal resistance. This device has the
added benefit of an efficient monolithic Schottky body diode.
