Overview

The NTF3055L108T1G is a logic-level N-Channel Power MOSFET designed for efficient switching in low-voltage applications. Housed in a compact SOT-223 package, it handles up to 60V and 3A while maintaining a low threshold voltage suitable for direct drive from microcontrollers.

Why Choose This Part

The device features a logic-level gate drive, allowing it to interface directly with 3.3V and 5V MCUs without an external gate driver. Its SOT-223 package provides a good balance between thermal performance and board space, supporting a wide operating junction temperature up to 175 degrees Celsius.

Applications

DC Motor Control
Driving small brushed DC motors in industrial and consumer robotics where logic-level control is required.
Power Supplies
Used as a high-side or low-side switch in DC-DC converters and voltage regulation circuits.
Solenoid Drivers
Efficiently switching inductive loads such as relays and solenoids in automated systems.
LED Lighting Control
PWM-based dimming and switching for low-voltage LED arrays.

Getting Started

When designing with this MOSFET, ensure the logic-level gate drive voltage accounts for the maximum Vgs(th) of 2V to guarantee full saturation. For high-speed PWM applications, calculate the gate charge requirements against the microcontroller's GPIO current sourcing capability to prevent switching losses.
