FAIRCHILD J March 1998 ## **FDN357N** ## **N-Channel Logic Level Enhancement Mode Field Effect Transistor** SuperSOTTM-3 N-Channel logic level enhancement mode power field effect transistors are produced using Fairchild's proprietary, high cell density, DMOS technology. This very high density process is especially tailored to minimize on-state resistance. These devices are particularly suited for low voltage applications in notebook computers, portable phones, PCMCIA cards, and other battery powered circuits where fast switching, and low in-line power loss are needed in a very small outline surface mount package. ~~ws a wi~~ **SOT-23** A **SuperSOTTM-6 SuperSOTTM-8** - 1.9 A, 30 V, RDS(ON) = 0.090 Ω @ VGS = 4.5 V RDS(ON) = 0.060 Ω @ VGS = 10 V. - Industry standard outline SOT-23 surface mount package using proprietary SuperSOTTM-3 design for superior thermal and electrical capabilities. - High density cell design for extremely low RDS(ON). Exceptional on-resistance and maximum DC current capability. **==> picture [175 x 7] intentionally omitted <==** **----- Start of picture text -----**
