General Description

These N-Channel enhancement mode power field effect
transistors are produced using Fairchild’s proprietary,

FQD19N1 0 / F Q U 1 9N10

planar stripe, DMOS technology.
This advanced technology has been especially tailored to
minimize on-state resistance, provide superior switching
performance, and withstand high energy pulse in the
avalanche and commutation mode. These devices are well
suited for low voltage applications such as audio amplifier,

Features

• 15.6A, 100V, R

• Low gate charge ( typical 19 nC)

• Low Crss ( typical 32 pF)

• Fast switching

• 100% avalanche tested

• Improved dv/dt capability

• RoHS Compliant
