General Description
This N-Channel MOSFET is produced using Fairchild
Semiconductor’s advanced Power Trench
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.
Applications
Synchronous Rectifier for DC/DC Converters
Telecom Secondary Side Rectification
High End Server/Workstation Vcore Low Side
