DMP31D1UDW-7

Overview

The DMP31D1UDW-7 is a dual P-channel enhancement mode MOSFET manufactured by Diodes Incorporated. It features a 25V drain-source breakdown voltage and supports a continuous drain current of 550mA per channel. The device utilizes an SOT-363 surface-mount package with six terminals. Key electrical characteristics include a maximum on-resistance of 900 milliohms and a gate-source voltage rating of ±8V. The component operates within a temperature range of -55°C to +150°C, with a power dissipation capacity of 600mW.

Feature Summary

• Dual independent P-channel configuration for compact circuit design
• Enhancement mode operation for standard logic control compatibility
• Low on-resistance for efficient power management in small packages

Applications

• Battery protection circuits
• Power switch applications
• Load switching in portable devices

Procurement Notes

Verify the specific datasheet revision and compliance documentation directly from Diodes Incorporated before integration. Confirm that the SOT-363 footprint matches the target PCB layout requirements. Ensure thermal management strategies account for the 600mW power dissipation limit under actual operating conditions. Cross-reference the part number suffix to confirm tape and reel specifications match assembly equipment capabilities.

Selection Notes

Select this component when a dual P-channel solution is required in a minimal footprint. The 25V rating suits low-voltage systems such as USB-powered devices or battery packs. Compare the 900mOhm resistance against single-channel alternatives if space allows, as dual configurations may offer higher total current handling. Evaluate the SOT-363 thermal performance against the expected duty cycle and ambient temperature constraints.

Part Context

This part belongs to the DMP series of P-channel MOSFETs from Diodes Incorporated. It is designed for general-purpose switching in consumer electronics and industrial control boards. The dual configuration reduces board space compared to using two separate single-channel transistors. It complements other components in power management subsystems requiring reliable low-side or high-side switching.

Replacement Considerations

Direct substitutes include other dual P-channel MOSFETs in SOT-363 packages with similar voltage and current ratings. Verify pinout compatibility and on-resistance values when considering alternatives from different manufacturers. Check for equivalent thermal characteristics and gate charge specifications to ensure switching performance remains consistent.
