DTC144EUA-TP

Overview

The DTC144EUA-TP is an NPN digital transistor manufactured by Micro Commercial Components (MCC) in a SOT-323 surface-mount package. It integrates built-in thin-film bias resistors to simplify circuit design. Key electrical specifications include a maximum supply voltage of 50 V, a collector current of 100 mA, and a power dissipation of 200 mW. The device features a typical input resistance (R1) of 47 kΩ with a resistance ratio (R2/R1) of 1.0. It offers a minimum DC current gain (hFE) of 68 and a transition frequency of 250 MHz. The component operates within a junction temperature range up to 150°C and is available in tape-and-reel packaging.

Feature Summary

• Built-in bias resistors enable inverter configuration without external input resistors
• Thin-film resistors provide complete isolation for negative biasing capability
• Eliminates parasitic effects associated with discrete resistor networks
• Simplifies device design by requiring only On/Off condition settings

Applications

• Inverter circuits
• Switching applications
• Logic interface circuits

Procurement Notes

Verify the authenticity of the DTC144EUA-TP by purchasing exclusively from Micro Commercial Components Corp or their authorized distributors. MCC does not assume liability for products acquired from unauthorized sources and provides no warranty coverage for such parts. Ensure that the ordering suffix matches the required packing quantity, such as -TP for 3Kpcs/Reel or -13P for 10Kpcs/Reel, as specified in the manufacturer's documentation.

Selection Notes

Select the DTC144EUA-TP when a compact NPN digital transistor with integrated biasing is required for space-constrained designs. The SOT-323 package suits surface-mount assembly processes. Consider the 47 kΩ input resistance and 1:1 resistor ratio for appropriate base drive requirements. Verify that the 50 V supply voltage and 100 mA collector current limits align with the target application's operational parameters.

Part Context

The DTC144EUA belongs to the DTC144 series of NPN digital transistors produced by Micro Commercial Components. This series utilizes thin-film technology for internal resistors, distinguishing it from standard bipolar junction transistors that require external biasing components. The device is part of MCC's portfolio of pre-biased transistors designed to reduce board space and simplify schematic design for switching and logic applications.
