DTC114ECAHE3-TP

Overview

The DTC114ECAHE3-TP is a single NPN digital transistor manufactured by Micro Commercial Components (MCC) in the 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 maximum collector-emitter voltage of 50 V and a continuous collector current of 100 mA. The device features typical base and emitter resistors of 10 kOhms each, with a minimum DC current gain (hFE) of 30 at 5 mA and 5 V. It operates within a junction temperature range up to 150°C and supports a transition frequency of 250 MHz.

Feature Summary

• Built-in thin-film bias resistors enable inverter configuration without external input resistors
• Resistors provide complete isolation allowing negative input biasing
• Halogen-free green device compliant with RoHS standards
• Qualified under AEC-Q101 automotive electronic standards

Applications

• Inverter circuits requiring simplified input stages
• Switching applications utilizing pre-biased control signals
• Automotive electronics systems meeting AEC-Q101 requirements

Procurement Notes

Verify component authenticity by purchasing exclusively from authorized MCC distributors or directly from the manufacturer. Unauthorized sources lack traceability and quality guarantees. Confirm the specific ordering suffix matches the required packaging format, such as tape reel quantities. Ensure compliance with environmental regulations like RoHS and REACH status before integration into final assemblies.

Selection Notes

Select this component when a single NPN digital switch with integrated 10kOhm bias resistors is required in an SOT-23 footprint. The device is suitable for designs needing negative biasing capability due to isolated thin-film resistors. Consider the 50V breakdown voltage and 100mA current limits against load requirements. Verify thermal dissipation needs against the 200mW power rating at specified ambient temperatures.

Part Context

This part belongs to the DTC114 series of digital transistors from Micro Commercial Components. It shares the fundamental architecture of integrated bias networks but differs in packaging and specific resistor values compared to other variants like the DTC114EUA-TP or DTC124ECAHE3-TP. The HE3 suffix indicates lead-free finish and RoHS compliance, while the ECA designation specifies the NPN configuration with 10kOhm/10kOhm resistor ratio.

Replacement Considerations

Direct substitutes include other DTC114 series parts with identical pinouts and electrical characteristics, such as the DTC114ECA-TP. Cross-reference packages carefully; alternatives like the DTC114EUA-TP utilize SOT-323 which requires layout adjustments. Verify that any replacement maintains the 10kOhm/10kOhm resistor ratio and meets AEC-Q101 qualification if automotive use is intended.
