DDTC123EUA-TP

Overview

The DDTC123EUA-TP is a digital transistor manufactured by Micro Commercial Components (MCC). It is an NPN pre-biased small signal surface mount transistor housed in a SOT-323 package. The device integrates biasing resistors, specifically R1 and R2, to simplify circuit design. It supports AEC-Q101 standards for automotive applications. Key electrical characteristics include a collector current of 100 mA and a supply voltage of 50 V. The component features built-in resistors with typical values of 2.2 kOhms for both base and emitter connections.

Feature Summary

• Integrates built-in biasing resistors to reduce external component count
• Designed for high reliability in automotive environments
• Supports AEC-Q101 qualification standards

Applications

• Automotive interface circuits
• Driver applications requiring compact solutions
• Inverter configurations using integrated biasing

Procurement Notes

Verify the specific suffix 'EUA' against the manufacturer's official datasheet to confirm pinout and resistor values. Ensure compliance with RoHS3 directives if required by the target market. Check for any recent Production Change Notices regarding packaging or assembly updates before finalizing procurement orders.

Selection Notes

Select this component when a compact NPN digital transistor with integrated biasing is required for space-constrained designs. The SOT-323 package offers a small footprint suitable for surface mount technology. Consider the 50 V rating and 100 mA current capacity to ensure adequate headroom for the intended switching or amplification application.

Part Context

This part belongs to the DDTC series of pre-biased transistors from MCC. It serves as a complement to the DTA series, which offers PNP types. The integration of resistors within the package distinguishes it from standard discrete bipolar junction transistors, providing a complete solution for basic logic inversion or switching tasks.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Verify compatibility with existing designs by comparing pinouts, electrical ratings, and package dimensions with alternative components from other manufacturers.
