DMN61D8LQ-13

Overview

The DMN61D8LQ-13 is an integrated N-channel MOSFET and inductive load driver manufactured by Diodes Incorporated. It provides a single-component solution for switching inductive loads such as relays, solenoids, and small DC motors in automotive applications without requiring external freewheeling diodes. The device accepts logic level inputs, allowing direct driving by logic gates, inverters, and microcontrollers. Key electrical parameters include a drain-source voltage (V_DSS) of 60 V, a maximum continuous drain current (I_D) of 470 mA at +25°C, and a static drain-source on-resistance (R_DS(ON)) of 1.8 Ω at V_GS = 5 V and 2.4 Ω at V_GS = 3 V. It features an internal active clamp to remove the need for external Zener diodes.

Feature Summary

• Integrates an N-channel MOSFET with an internal active clamp circuit, eliminating the requirement for external freewheeling or Zener diodes when switching inductive loads.
• Accepts logic level inputs, enabling direct interfacing with sensitive logic circuits, microcontrollers, and inverters.
• Replaces three to four discrete components, significantly reducing printed circuit board footprint while providing a robust interface between logic and DC relay coils.

Applications

• Switching automotive relays
• Driving solenoids
• Controlling small DC motors

Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm that the specific order suffix matches the required packaging quantity, as the -13 suffix indicates a tape and reel configuration. Ensure compliance with AEC-Q101 qualification standards if the application demands high reliability. Review the datasheet for thermal resistance values under different PCB mounting conditions to validate power dissipation capabilities.

Selection Notes

Select this component for designs requiring a compact, single-chip solution for low-current inductive loads. It is suitable for applications where space constraints prevent the use of multiple discrete components. Verify that the gate drive voltage meets the threshold requirements for the desired on-resistance. Consider the thermal performance characteristics based on the specific PCB copper coverage and layout used in the final design.
