DTC144EUAHE3-TP

Overview

The DTC144EUAHE3-TP is an NPN digital transistor manufactured by Micro Commercial Components (MCC). It integrates a single NPN bipolar junction transistor with internal biasing resistors within a compact SOT-523 surface-mount package. The device features a collector-emitter breakdown voltage of 50 V and a maximum continuous collector current of 100 mA. Internal resistor values are specified as R1 = 47 kOhms and R2 = 47 kOhms, resulting in a resistance ratio of 1. Key electrical characteristics include a minimum DC current gain (hFE) of 68 at 5 mA and 5 V, a transition frequency of 250 MHz, and a maximum power dissipation of 150 mW.

Feature Summary

• Integrates NPN transistor with dual biasing resistors for simplified circuit design
• Optimized for high-speed switching applications with defined transition frequency
• Compliant with RoHS directives and halogen-free manufacturing standards

Applications

• General-purpose switching circuits
• Driver stages for logic interfaces
• Level shifting between different voltage domains

Procurement Notes

Verify the specific suffix HE3 against the manufacturer's latest datasheet to confirm compliance with environmental regulations such as RoHS and REACH. Ensure the ordering quantity aligns with the available packaging formats, typically reel or cut tape, as distribution availability may vary by region. Cross-reference the part number with official distributor catalogs to confirm current production status and lead times before finalizing procurement plans.

Selection Notes

Select this component when a compact NPN digital transistor with equal base and emitter biasing resistors is required. The SOT-523 package offers space efficiency compared to larger footprints. Verify that the 50 V collector-emitter voltage rating and 100 mA current capacity meet the specific load requirements of the target application circuit.

Part Context

This part belongs to the DTC144EUA series of pre-biased transistors from Micro Commercial Components. It shares functional similarities with other members of the DTC144 family but differs in packaging and specific environmental qualifications indicated by the HE3 suffix. The device serves as a direct replacement for standard discrete resistor-transistor networks in space-constrained designs.

Replacement Considerations

Direct substitutes include DTC144EUA-TP and DTC144EE-TP, provided the package type and electrical parameters match the design requirements. Verify pinout compatibility and thermal characteristics when swapping between SOT-323 and SOT-523 packages.
