General Description
This N-Channel MOSFET is produced using Fairchild
Semiconductor’s advanced PowerTrench
®
process.
Advancements in both silicon and Dual Cool
TM
package
technologies have been combined to offer the lowest r
DS(on)
while maintaining excellent switching performance by extremely
low Junction-to-Ambient thermal resistance.
