FQP4N90C / FQPF4N90C — N-Channel QFET® MOSFET FQP4N90C / FQPF4N90C N-Channel QFET® MOSFET 900 V, 4.0 A, 4.2 Ω December 2013 Description This N-Channel enhancement mode power MOSFET is produced using Fairchild Semiconductor’s proprietary planar stripe and DMOS technology. This advanced MOSFET technology has been especially tailored to reduce on-state resistance, and to provide superior switching performance and high avalanche energy strength. These devices are suitable for switched mode power supplies, active power factor correction (PFC), and electronic lamp ballasts. Features • 4.0 A, 900 V, RDS(on) = 4.2 Ω (Max.) @ VGS = 10 V, ID = 2.0 A • Low Gate Charge (Typ. 17 nC) • Low Crss (Typ. 5.6 pF) • 100% Avalanche Tested D GDS TO-220 GDS TO-220F G S Absolute Maxim [ ... ]
