The NDS351AN from onsemi is a 30V 2A N-channel MOSFET with 80mOhm RDS(on) in SOT-23 for low-power switching and load driving.
The NDS351AN is an N-channel enhancement-mode MOSFET from onsemi/Fairchild in SOT-23, rated at 30V drain-source voltage and 2A drain current with 80mOhm RDS(on) at VGS=4.5V. The trench-gate technology creates vertical channels in the silicon, maximizing channel width per unit area to achieve the low 80mOhm on-resistance in a small SOT-23 die. The gate threshold voltage (Vth) is typically 1.0V, allowing logic-level drive from 2.5V or 3.3V MCUs. At VGS=2.5V, RDS(on) increases to approximately 120mOhm, still very low for a SOT-23 device. The total gate charge is 6.5nC at 4.5V, enabling switching frequencies up to several hundred kHz with modest gate drive current. The 30V rating limits applications to 3.3V and 5V power rails, but the 2A current rating and low RDS(on) make it excellent for load switching, battery disconnect, and DC-DC converter low-side switching in portable devices. The continuous drain current is derated based on thermal limits: the SOT-23 package has thermal resistance of approximately 250C/W on FR-4 PCB, so maximum practical continuous current at 70C ambient is approximately 1.5A.
