NDP708A NDP708AE NDP708B NDP708BE NDB708A NDB708AE NDB708B NDB708BE N-Channel Enhancement Mode Field Effect Transistor
These N-channel enhancement mode power field effect transistors produced using Fairchild's proprietary, high cell density, DMOS technology. This very high density process been especially tailored minimize on-state resistance, provide superior switching performance, withstand high energy pulses avalanche commutation modes. These devices particularly suited voltage applications such automotive, DC/DC converters, motor controls, other battery powered circuits where fast switching, in-line power loss, resistance transients needed.
Features
54A, 80V. RDS(ON) 0.022 0.025. Critical electrical parameters specified elevated temperature. Rugged internal source-drain diode eliminate need external Zener diode transient suppressor. 175°C maximum junction temperature rating. High density cell design extremely RDS(ON). TO-220 TO-263 (D2PAK) package both through hole surface mount applications.
