Overview

The ZXMN7A11GQTA is an automotive-qualified N-channel MOSFET designed by Diodes Incorporated, featuring a 70V drain-source voltage rating and a 2.7A continuous drain current at 25 degrees Celsius. It is housed in a compact SOT-223 package, making it suitable for space-constrained power management and switching tasks. This component is AEC-Q101 qualified, ensuring high reliability in harsh environments.

Why Choose This Part

The device offers a low gate threshold voltage of 1V, allowing it to be driven directly by many low-voltage microcontrollers. Its SOT-223 package provides a balance between thermal performance and board area, supporting up to 2W of power dissipation. Furthermore, its AEC-Q101 qualification makes it a robust choice for automotive-grade reliability.

Applications

DC-DC Converters
High-efficiency power conversion in automotive and industrial systems requiring a 70V breakdown voltage.
Motor Control
Driving small brushed DC motors or stepper motor phases in automotive body electronics.
Disconnect Switches
Acting as a high-side or low-side load switch for power rail management and battery isolation.
Class-D Audio Output
Utilized in the output stages of audio amplifiers due to its fast switching characteristics.

Getting Started

When designing with this MOSFET, ensure adequate PCB copper area is provided around the drain tab of the SOT-223 package to manage the 2W thermal dissipation limit. Use a standard logic-level gate driver or a direct MCU GPIO pin, keeping in mind the +/-20V Vgs limit and the 130mOhm RDS(on) at 10V gate drive.
