Overview
The DMN4040SK3Q-13 is a surface-mount N-channel enhancement mode MOSFET manufactured by Diodes Incorporated. It features a 40V drain-source voltage rating and supports a continuous drain current of 6A at ambient temperature. The device utilizes a TO-252-3 (DPAK) package with a maximum power dissipation of 1.71W. Key electrical characteristics include a maximum on-resistance of 30 milliohms at 10V gate drive, a gate charge of 18.6nC, and an input capacitance of 945pF. It operates within a junction temperature range of -55°C to 150°C and holds AEC-Q101 automotive qualification.
Feature Summary
- Automotive-grade reliability certified under the AEC-Q101 standard for robust performance in vehicle electronics.
- Optimized low on-resistance design facilitates efficient power switching and reduced conduction losses.
- Enhanced thermal management capabilities inherent to the DPAK package structure support stable operation.
Applications
- Automotive load switch circuits requiring high reliability
- Power distribution units in vehicle electronic systems
- General-purpose power switching applications
Procurement Notes
Verify that the ordering suffix Q-13 explicitly denotes AEC-Q101 automotive qualification status as per manufacturer documentation. Confirm the specific tape and reel packaging configuration matches production requirements. Ensure component authenticity through authorized supply channels to guarantee compliance with specified electrical parameters and quality standards.
Selection Notes
Select this component when automotive certification is mandatory for the target application. The 40V rating suits low-voltage automotive systems. Evaluate thermal constraints carefully given the 1.71W dissipation limit. Compare gate charge specifications against driver capabilities to ensure adequate switching speed without excessive drive current demands.
Part Context
This part belongs to the DMN4040 series of N-channel MOSFETs from Diodes Incorporated. The series focuses on providing reliable switching solutions for automotive environments. The SK3 designation typically indicates specific internal process or packaging variations within the broader product family line.
Replacement Considerations
Direct substitutes must match the 40V rating, N-channel type, TO-252-3 package, and AEC-Q101 qualification. Verify equivalent on-resistance and thermal performance before implementation.
