DTC114EUAHE3-TP

Overview

The DTC114EUAHE3-TP is a single NPN digital transistor manufactured by Micro Commercial Components (MCC). It integrates internal bias resistors with a typical base resistance of 10 kOhms and an emitter resistance ratio of 1. The device features a collector-emitter breakdown voltage of 50 V and supports a continuous collector current of 100 mA. It operates within a temperature range of -55°C to +150°C and dissipates up to 200 mW of power. The component is housed in an SOT-323-3 surface-mount package and holds AEC-Q101 automotive qualification.

Feature Summary

• Integrates dual bias resistors to simplify circuit design and reduce board space.
• Automotive-grade reliability certified under the AEC-Q101 standard.
• High thermal stability supporting operation at junction temperatures up to 150°C.

Applications

• Switching applications in automotive electronic control units.
• Driver circuits for low-power loads in vehicle systems.
• Logic level translation and buffering in embedded automotive modules.

Procurement Notes

Verify the specific suffix HE3 against official MCC documentation to confirm halogen-free status and RoHS compliance before procurement. Confirm that the AEC-Q101 qualification aligns with target automotive application requirements. Ensure the SOT-323-3 footprint matches the PCB layout specifications. Validate supply chain authenticity through authorized distributors to prevent counterfeit components.

Selection Notes

Select this component when a single NPN digital transistor with integrated 10 kOhm base biasing is required. The 50 V collector-emitter voltage rating suits low-voltage switching tasks. The SOT-323-3 package offers a compact solution for space-constrained designs. Consider the 100 mA continuous current limit for load driving capabilities. Verify thermal management needs given the 200 mW power dissipation rating.

Part Context

This part belongs to the DTC114EUA series of pre-biased transistors from Micro Commercial Components. It shares the same electrical characteristics and pinout as the DTC114EUA-TP, with the HE3 suffix indicating specific environmental compliance attributes. The series is designed for general-purpose switching and amplification in consumer and automotive electronics.

Replacement Considerations

The DTC114EUA-TP serves as a direct functional equivalent within the same product line. Cross-referencing with other manufacturers' NPN digital transistors requires matching the 10 kOhm base resistor value, 50 V Vceo, and SOT-323 package dimensions to ensure compatibility.
