DMB54D0UDW-7

Overview

The DMB54D0UDW-7 is a dual transistor array housed in a SOT-363 surface-mount package. It integrates one N-channel enhancement mode MOSFET and one PNP bipolar junction transistor. The N-channel MOSFET supports a drain-source voltage of 50V with a continuous drain current of 160mA. The PNP transistor provides a collector-emitter voltage rating of 45V and a continuous collector current of 100mA. This configuration is designed for automotive applications requiring compact switching solutions.

Feature Summary

• Integrates an N-channel MOSFET and a PNP transistor in a single compact package
• Designed specifically for automotive electronic applications
• Features very low gate threshold voltage to facilitate efficient drive control

Applications

• Automotive circuit protection modules
• Low-side switching applications in vehicle electronics
• General purpose signal switching in automotive control units

Procurement Notes

Verify the component status carefully, as this part number is listed as End of Life and scheduled for obsolescence by the manufacturer. Ensure that any sourced inventory matches the specific -7 suffix for tape and reel packaging. Confirm RoHS compliance and check for date code restrictions when sourcing from third-party distributors to guarantee authenticity and storage history integrity.

Selection Notes

Select this component when a combined N-MOSFET and PNP transistor solution is required within strict space constraints typical of automotive PCB layouts. The SOT-363 package offers a small footprint suitable for high-density designs. Consider the specific voltage and current ratings of both internal devices to ensure they meet the load requirements of the target application circuit without exceeding absolute maximum ratings.

Part Context

This device belongs to the DMB series of special purpose transistors manufactured by Diodes Incorporated. These components are engineered to replace multiple discrete components, thereby reducing board space and assembly complexity. The integration of complementary N-channel and PNP devices allows for efficient implementation of logic gates or level-shifting circuits in a standardized surface-mount form factor.

Replacement Considerations

Due to the End of Life status, direct substitutes must be identified based on matching pinout, electrical parameters, and package type. Verify that alternative components support the same automotive qualification standards if the original design intent requires it. Cross-reference datasheets to ensure equivalent Vds, Vce, and current capabilities before finalizing any replacement strategy.
