| FDS8433A September 2000 FDS8433A Single P-Channel 2.5V Specified MOSFET General Description This P-Channel enhancement mode power field effect transistors is produced using Fairchild's proprietary, high cell density, DMOS technology. This very high density processis especially tailored to minimize on-state resistance and provide superior switching performance. Features * -5 A, -20 V. RDS(on) = 0.047 @ VGS = -4.5 V RDS(on) = 0.070 @ VGS = -2.5 V * * * Fast switching speed. High density cell design for extremely low RDS(on). High power and current handling capability.
