FQD2P40 / FQU2P40 is a 400V P-Channel MOSFET, using Fairchild's proprietary planar stripe DMOS technology, with extremely low on-state resistance, fast switching speed and high voltage resistance, suitable for electronic lamp ballasts.
The document describes the FQD2P40 / FQU2P40, which are 400V P-Channel enhancement mode power MOSFETs produced using Fairchild's proprietary planar stripe DMOS technology. These devices are designed to minimize on-state resistance and provide superior switching performance, making them well-suited for electronic lamp ballasts based on complementary half bridge topology.
