DMN61D8LQ-7

Overview

The DMN61D8LQ-7 is an integrated relay 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 (BVDSS) of 60V, a maximum continuous drain current (ID) of 470mA at +25°C, and a static drain-source on-resistance (RDS(ON)) of 1.8Ω at VGS = 5V or 2.4Ω at VGS = 3V.

Feature Summary

• Provides a reliable and robust interface between sensitive logic circuits and DC relay coils
• Replaces multiple discrete components to enable significant PCB footprint reduction
• Features an internal active clamp that eliminates the need for external Zener diodes

Applications

• Switching DC relay coils in automotive systems
• Driving solenoid loads
• Controlling small DC motors

Procurement Notes

Verify the specific ordering suffix '-7' corresponds to the 3,000-unit tape and reel packaging configuration. Confirm AEC-Q101 qualification status and PPAP capability requirements are met for the target automotive application. Ensure the selected component matches the SOT23 package dimensions and lead-free plating specifications defined in the datasheet.

Selection Notes

Select this component when designing circuits that require switching inductive loads directly from logic-level control signals. It is suitable for applications needing a compact solution that integrates protection features typically provided by discrete components. Consider the thermal resistance and power dissipation limits relative to the expected duty cycle and ambient temperature conditions.

Part Context

This part belongs to the DMN61D8LQ series of integrated drivers designed specifically for automotive environments. It is engineered to handle inductive switching transients and reverse battery conditions, offering high reliability through AEC-Q101 qualification. The device consolidates functions usually distributed across several discrete parts into a single surface-mount package.
