HUF76112SK8
Data Sheet
December 2001
7.5A, 30V, 0.026 Ohm, N-Channel, Logic
Level Power MOSFET
The HUF76112SK8 is an Application-Specific MOSFET
optimized for switching when used as the upper switch in
synchronous buck applications. The low gate charge and low
input capacitance results in lower driver and lower switching
losses, thereby increasing the overall system efficiency.
