FQP8N60/FQPF8N60 600V N-Channel MOSFET Features ■ 7.5A,600V,RDS(on)=1.0Ω@VGS=10V ■ Low gate charge ■ Low Crss (typical 23pF) ■ Fast switching ■ 100% AvalancheTested ■ Improved dv/dt capability ■ ROHS product General Description This Power MOSFET is produced using AOKE’s advanced planar stripe, DMOS technology. This latest technology has been especially designed to minimize on-state resistance, have a high rugged avalanche characteristics. These devices are well suited for high efficiency switch mode power supplies, active power factor correction, electronic lamp ballasts based on half bridge topology.
