Overview

The NTR4501NT1G is an N-Channel Power MOSFET designed for efficient power management and switching in space-constrained applications. It offers a low drain-to-source resistance of 80mOhm at 4.5V gate drive and can handle continuous drain currents up to 3.2A. Its SOT-23 footprint makes it suitable for low-profile consumer and industrial electronics.

Why Choose This Part

This MOSFET features leading planar technology for low gate charge and fast switching speeds, reducing power losses. It is specifically rated for 2.5V operation, allowing it to be driven directly by low-voltage microcontrollers. The SOT-23 package provides a reliable surface mount solution with a maximum power dissipation of 1.25W.

Applications

Load Switching
Used as a high-side or low-side switch to manage power rails in battery-operated devices.
DC-DC Conversion
Acts as a switching element in compact buck or boost converters requiring low voltage gate drive.
Battery Management
Provides efficient charge and discharge control in portable electronics due to its low on-resistance.
Signal Level Shifting
Translates logic signals between different voltage domains thanks to its low 1.2V gate threshold.

Getting Started

When integrating this MOSFET, ensure the gate-to-source voltage does not exceed the +/-12V limit. Use standard PCB footprints for SOT-23 (TO-236) and provide sufficient copper pour around the drain pin to manage thermal dissipation. No specialized software or IDE is required for this discrete component.
