Overview
The AOB2144L is a 40V N-Channel MOSFET utilizing Trench Power MV technology. It features a maximum drain-source voltage of 40V and a continuous drain current of 120A at 25°C case temperature. The device offers a low on-resistance of less than 2.3mΩ at VGS=10V and less than 4mΩ at VGS=4.5V. Packaged in TO-263, it supports high thermal performance with a junction-to-case resistance of 0.8°C/W and operates within a temperature range of -55°C to 175°C.
Feature Summary
- Utilizes advanced Trench Power MV technology for optimized electrical performance.
- Features low gate charge characteristics suitable for efficient switching applications.
- Demonstrates optimized ruggedness verified through 100% Unclamped Inductive Switching (UIS) testing.
Applications
- DC Motor Driver
- Synchronous Rectification in DC/DC Converters
- Synchronous Rectification in AC/DC Converters
Procurement Notes
Verify the specific package configuration required for the design, as the AOB2144L designation corresponds to the TO-263 Tape & Reel form factor. Confirm that the application environment remains within the specified operating temperature limits and thermal dissipation constraints defined in the datasheet. Ensure compatibility with standard surface-mount assembly processes.
Selection Notes
Select this component for designs requiring high current handling capability up to 120A with minimal conduction losses. The low on-resistance values at both 10V and 4.5V gate drive voltages make it adaptable for various logic-level control schemes. Consider the thermal management requirements associated with the TO-263 package to ensure reliable operation under load.
Part Context
This part belongs to the AOS lineup of N-Channel MOSFETs designed for power switching applications. It shares the core trench technology architecture with other devices in the series but is distinguished by its specific 40V rating and high-current capacity. The TO-263 packaging facilitates effective heat dissipation for power-intensive circuits.
Replacement Considerations
The AOT2144L is an electrically identical alternative available in a TO-220 tube package. When substituting, verify that the mechanical footprint and mounting style of the target PCB accommodate the different package type. Electrical parameters remain consistent between the two variants.
