DMN66D0LDWQ-7

Overview

The DMN66D0LDWQ-7 is a dual N-channel enhancement mode MOSFET in an SOT363 package, qualified to AEC-Q101 for automotive use. It features a 60V drain-source voltage and low on-resistance of 5Ω at VGS=10V and 6Ω at VGS=5V. Continuous drain current reaches 217mA at +25°C. The device includes ESD protected gates, operates from -55°C to +150°C, and offers fast switching with low input capacitance.

Feature Summary

• Dual N-channel configuration with integrated gate protection diodes
• AEC-Q101 qualified for automotive reliability standards
• Low on-resistance and low gate threshold voltage for efficient switching
• Totally lead-free and RoHS compliant green device

Applications

• Load switch circuits
• Automotive electronic control units
• Low power signal routing

Procurement Notes

Verify the specific ordering suffix (-7 or -13) matches the required tape and reel quantity. Confirm that the SOT363 package dimensions align with your PCB footprint requirements. Ensure the design accounts for the thermal resistance values provided for FR-4 substrates to maintain junction temperature within safe operating limits during continuous operation.

Selection Notes

Select this component when a compact dual N-channel solution is required for automotive environments. The low gate threshold voltage facilitates drive from 3.3V or 5V logic sources. Consider the small SOT363 form factor for space-constrained designs where dual independent channels are needed without increasing board area.

Part Context

This part belongs to Diodes Incorporated's DMN series of dual MOSFETs. It is manufactured in IATF 16949 certified facilities to support automotive supply chain requirements. The device is designed to replace single-channel solutions by providing two isolated switches in a minimal footprint, reducing component count in load management applications.

Replacement Considerations

Check pinout compatibility if substituting other SOT363 dual MOSFETs. Verify that alternative parts meet the same AEC-Q101 qualification level if used in safety-critical automotive systems. Ensure the replacement maintains similar RDS(ON) characteristics to preserve power efficiency.
