FDS6894AZ October 2001 FDS6894AZ Dual N-Channel Logic Level PWM Optimized PowerTrench® MOSFET General Description These N-Channel Logic Level MOSFETs are produced using Fairchild Semiconductor’s advanced PowerTrench process that has been especially tailored to minimize the 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. Features • 8 A, 20 V.
