DMN4031SSDQ-13

Overview

The DMN4031SSDQ-13 is a dual N-channel enhancement mode MOSFET manufactured by Diodes Incorporated. It features a SO-8 surface-mount package and meets AEC-Q101 automotive qualification standards with PPAP capability. The device provides a drain-source breakdown voltage of 40V and supports a continuous drain current up to 7.0A at 25°C (VGS=10V). Static on-resistance is specified as 31mΩ maximum at VGS=10V and 50mΩ maximum at VGS=4.5V. Total power dissipation reaches 2.6W on high-copper PCBs, with an operating temperature range from -55°C to +150°C.

Feature Summary

Qualified for automotive applications under AEC-Q101 standards
Low on-resistance for efficient power management
Lead-free and RoHS compliant construction

Applications

Motor controls
Backlighting circuits
Power-management functions
DC-DC converters

Procurement Notes

Verify the component against the official datasheet DS37995 Rev. 5-2 to confirm authenticity. Ensure the part number matches DMN4031SSDQ-13 exactly. Check that the marking code reads N4031SD. Confirm compliance with automotive quality requirements if used in such environments.

Selection Notes

Select this component when a dual N-channel solution is required for automotive-grade designs. Consider the 40V rating and low on-resistance characteristics for switching efficiency. Verify thermal performance based on specific PCB copper coverage and ambient conditions.

Part Context

This part belongs to the DMN4031 series of dual N-channel MOSFETs from Diodes Incorporated. It shares the SO-8 package form factor with other devices in the family but offers specific electrical parameters tailored for automotive power applications.

Replacement Considerations

No official substitutes are listed in the documentation. When evaluating alternatives, verify matching pinout configurations, voltage ratings, and thermal resistance values to ensure compatibility.
