DTC143EUA-TP

Overview

The DTC143EUA-TP is an NPN digital transistor from Micro Commercial Components, housed in a SOT-323 surface-mount package. It integrates internal biasing resistors to simplify circuit design. Key electrical specifications include a maximum supply voltage of 50V and a collector current rating of 100mA. The device features a typical input resistance (R1) of 4.7 kΩ with a resistance ratio (R2/R1) of 1.0. It operates with a transition frequency of 250 MHz and supports a power dissipation of 200 mW at 25°C. The junction temperature range extends up to 150°C.

Feature Summary

• Integrates built-in biasing resistors for simplified circuit implementation
• Utilizes epitaxial planar die construction for reliable performance
• Complies with RoHS standards and contains no halogen compounds

Applications

• Switching applications requiring integrated biasing
• High-frequency signal processing circuits
• General-purpose digital logic interfacing

Procurement Notes

Verify the component authenticity by checking the marking code '23' on the device body against official MCC documentation. Ensure the ordering suffix '-TP' corresponds to the Tape & Reel packaging format containing 3,000 pieces per reel as specified in the manufacturer's ordering information. Confirm compliance with UL 94 V-0 flammability ratings if required for the specific application environment.

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 high-density PCB layouts. Consider the 4.7 kΩ input resistance and 1:1 resistor ratio for standard logic interface requirements. Ensure the operating voltage does not exceed the 50V maximum rating and that thermal management accommodates the 200 mW power dissipation limit.

Part Context

This part belongs to the DTC143EUA series of NPN digital transistors manufactured by Micro Commercial Components. The series is designed for general-purpose switching and amplification tasks where external biasing components can be eliminated. The device is marketed as a 'Green' product, indicating it meets specific environmental criteria regarding halogen content.

Replacement Considerations

Cross-reference with other NPN digital transistors in the SOT-323 package having similar R1 values (approx. 4.7 kΩ) and Vceo ratings (50V). Verify pinout compatibility (Base, Collector, Emitter) and electrical characteristics such as hFE and fT before substitution.
