DTC114ECA-TP

Overview

The DTC114ECA-TP is an NPN digital transistor manufactured by Micro Commercial Components (MCC) in a SOT-23 surface-mount package. It integrates bias resistors to simplify circuit design, eliminating the need for external input components. Key electrical specifications include a supply voltage of 50 V, continuous output current of 50 mA, and pulsed collector current up to 100 mA. The device features a typical transition frequency of 250 MHz and a DC current gain of 35. Internal resistors R1 and R2 are typically 10 kΩ each with a ratio of 1.0. Power dissipation is rated at 246 mW, operating within a temperature range of -55°C to +150°C.

Feature Summary

• Built-in thin-film bias resistors enable inverter configuration without external input resistors.
• Resistors provide complete isolation to allow negative input biasing and minimize parasitic effects.
• Halogen-free 'Green' device compliant with UL 94 V-0 flammability ratings.
• Moisture Sensitivity Level 1 classification.

Applications

• Inverter circuits requiring simplified input stages
• Switching applications utilizing on/off condition control
• General-purpose digital logic interfacing

Procurement Notes

Verify authenticity through authorized MCC distributors or direct purchase to avoid counterfeit risks. Confirm RoHS compliance via the "P" suffix designation. Ensure storage conditions align with Moisture Sensitivity Level 1 requirements. Check datasheet revisions for potential parameter updates before finalizing procurement specifications.

Selection Notes

Select this component for designs needing integrated biasing to reduce board space and component count. Verify that the 50 V supply voltage and 50 mA continuous current meet system requirements. Consider the 250 MHz transition frequency for high-speed switching needs. Ensure thermal management supports the 246 mW power dissipation rating at expected ambient temperatures.

Part Context

This part belongs to the DTC114 series of single NPN digital transistors. It is functionally complementary to PNP variants like the DTA114ECA. The device is designed for surface-mount assembly in compact electronic systems where space efficiency and simplified biasing are prioritized over discrete resistor configurations.

Replacement Considerations

Direct functional substitutes include other NPN digital transistors with similar 50V ratings and integrated 10kΩ bias resistors in SOT-23 packages. Verify pinout compatibility and electrical parameters such as hFE and fT before substitution.
