DMB53D0UV-7

Overview

The DMB53D0UV-7 is a dual-transistor component manufactured by Diodes Incorporated, integrating one NPN bipolar junction transistor and one N-channel enhancement-mode MOSFET within a single SOT-563 surface-mount package. The device features a maximum drain-source voltage of 50 V for the MOSFET section and a collector-emitter voltage rating of 45 V for the NPN section. It supports continuous current ratings of 160 mA for the N-channel MOSFET and 100 mA for the NPN transistor. The unit operates across an extended temperature range from -55°C to +150°C with a power dissipation capacity of 225 mW.

Feature Summary

• Integrates complementary NPN and N-channel MOSFET structures in a compact footprint
• Provides independent switching capabilities for logic control and load driving
• Designed for surface-mount assembly using standard reflow processes

Applications

• General-purpose signal switching circuits
• Logic level translation interfaces
• Driver stages for low-power loads

Procurement Notes

Verify the specific suffix against official manufacturer documentation to confirm pinout compatibility and electrical characteristics. Confirm RoHS compliance status through current datasheets as regulatory requirements may evolve. Ensure the selected variant matches the required thermal management specifications for the intended enclosure design.

Selection Notes

Select this component when space constraints require combining discrete NPN and NMOS functions into a single package. Evaluate the combined power dissipation limits against the total heat generated by both transistors during simultaneous operation. Verify that the 50V breakdown voltage meets the system's peak voltage requirements.

Part Context

This part belongs to the DMB53 series of dual-transistor arrays produced by Diodes Incorporated. These components are engineered to reduce board space and simplify assembly by replacing multiple discrete devices. The SOT-563 package offers a standardized footprint compatible with automated pick-and-place manufacturing equipment.

Replacement Considerations

Public records indicate the DMB53D0UV-7 has reached end-of-life status. Designers should consult official substitution guides for verified alternatives such as the DMB53D0UVDIDKR or other compatible dual-transistor packages from the same manufacturer family.
