NDH8503N Dual N-Channel Enhancement Mode Field Effect Transistor
SuperSOT N-Channel enhancement mode power field effect transistors produced using Fairchild's proprietary, high cell density, DMOS technology. This very high density process especially tailored minimize on-state resistance. These devices particularly suited voltage applications such notebook computer power management, other battery powered circuits where fast switching, in-line power loss needed very small outline surface mount package.
