DTC123ECA-TP

Overview

The DTC123ECA is an NPN digital transistor in a SOT-23 package, featuring built-in biasing resistors R1 and R2. It operates with a supply voltage up to 50V and input voltage up to 12V. The device supports an output current of 100mA with a power dissipation of 200mW at 25°C. Key electrical parameters include an input resistance (R1) typified at 2.2kΩ, a transition frequency of 250MHz, and a DC current gain of 20. The internal structure integrates the transistor with resistive components for simplified circuit design.

Feature Summary

• Epitaxial planar die construction for reliable performance
• Integrated biasing resistors simplify circuit layout
• RoHS compliant and halogen-free green device
• Moisture sensitivity level 1 classification

Applications

• Switching applications requiring integrated biasing
• Driver circuits for low-power loads
• Logic interface buffering

Procurement Notes

Verify authenticity by purchasing directly from Micro Commercial Components or authorized distributors. Counterfeit parts pose significant risks; MCC does not warrant products from unauthorized sources. Ensure the ordering suffix matches specifications, as changes may affect compliance or packaging details without altering core function unless explicitly stated in official documentation.

Selection Notes

Select this component when an NPN digital transistor with specific biasing ratios is required. The typical input resistance of 2.2kΩ and resistance ratio of 1.0 suit standard logic interfacing. Consider the SOT-23 package constraints for thermal management, noting the 200mW power dissipation limit at 25°C ambient temperature.

Part Context

This part belongs to the DTC series of digital transistors manufactured by Micro Commercial Components. These devices combine bipolar junction transistors with on-chip resistors to reduce board space and assembly costs. The ECA designation typically indicates specific pinout and electrical characteristics within the product family.

Replacement Considerations

Publicly confirmed substitute part numbers are not provided in the source material. Engineers should consult manufacturer cross-reference guides or equivalent datasheets for compatible alternatives that match the SOT-23 package and electrical specifications.
