IRFS634B

IRF634B/IRFS634B November 2001 IRF634B/IRFS634B 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 converters and switch mode power supplies. Features 8.1A, 250V, RDS(on) = 0.45Ω @VGS = 10 V Low gate charge ( typical 29 nC) Low Crss ( typical 20 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) IRF634B 250 8.1 5.1 32.4 ± 30 (Note 2) (Note 1) (Note 1) (Note 3) IRFS634B 8.1 * 5.1 * 32.4 * 200 8.1 7.4 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 74 0.59 -55 to +150 300 38 0...
