IRFS644B

IRF644B/IRFS644B November 2001 IRF644B/IRFS644B 250V N-Channel MOSFET General Description These N-Channel enhancement mode power field effect transistors are produced using Fairchild’s proprietary, planar, 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 high efficiency switching DC/DC converter and switch mode power supplies. Features 14A, 250V, RDS(on) = 0.28Ω @VGS = 10 V Low gate charge ( typical 47 nC) Low Crss ( typical 30 pF) Fast switching 100% avalanche tested Improved dv/dt capability D G G DS TO-220 IRF Series GD S TO-220F IRFS Series S Absolute Maximum Ratings Symbol VDSS ID IDM VGSS EAS IAR EAR dv/dt PD TJ, TSTG TL TC = 25°C unless otherwise noted Parameter Drain-Source Voltage - Continuous (TC = 25°C) Drain Current - Continuous (TC = 100°C) Drain Current - Pulsed (Note 1) IRF644B 250 14 8.9 56 ± 30 (Note 2) (Note 1) (Note 1) (Note 3) IRFS644B 14 * 8.9 * 56 * 480 14 13.9 5.5 Units V A A A V mJ A mJ V/ns W W/°C °C °C Gate-Source Voltage Single Pulsed Avalanche Energy Avalanche Current Repetitive Avalanche Energy Peak Diode Recovery dv/dt Power Dissipation (TC = 25°C) - Derate above 25°C Operating and Storage Temperature Range Maximum lead temperature for soldering purposes, 1/8" from case for 5 seconds 139 1.11 -55 to +150 300 43 0.35 * ...
