General Description
These dual N and P-Channel enhancement mode power
MOSFETs are produced using Fairchild Semiconductor’s
advanced PowerTrench process that has been especially
tailored to minimize on-state resistance and yet maintain
superior switching performance.
These devices are well suited for low voltage and battery
powered applications where low in-line power loss and fast
switching are required.
