SVF3N80M/F/D_Datasheet 3A, 800V N-CHANNEL MOSFET GENERAL DESCRIPTION SVF3N80M/F/D is an N-channel enhancement mode power MOS field effect transistor which is produced using Silan proprietary F-CellTM structure VDMOS technology. The improved planar stripe cell and the improved guard ring terminal have 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 widely used in AC-DC power suppliers, DCDC converters and H-bridge PWM motor drivers. FEATURES ∗ 3A, 800V, RDS(on)(typ.)=3.8Ω@VGS=10V ∗ Low gate charge ∗ Low Crss ∗ Fast switching ∗ Improved dv/dt capability NOMENCLATURE ORDERING INFORMATION Part No. SVF3N80M SVF3N80F SVF3N80D SVF3N80DTR Package [ ... ]
