Procurement Notes

Verify authenticity by purchasing directly from Micro Commercial Components or authorized distributors. Counterfeit parts pose significant risks; ensure full traceability and compliance with MCC quality standards for handling and storage before integration into designs.

Selection Notes

Select this component for NPN digital switching needs requiring integrated biasing. The SOT-323 package suits space-constrained layouts. Ensure input voltage limits (-40V to +6V) are respected. The 10kΩ base resistor and 4.7 ratio define drive characteristics suitable for standard logic interfaces.

Part Context

This part belongs to the DTA114 series of pre-biased transistors from Micro Commercial Components. It integrates a BJT with internal resistors to simplify circuit design. The 'HE3' suffix indicates RoHS compliance and halogen-free construction, aligning with modern environmental regulations for electronic components.

Replacement Considerations

Check pinout compatibility and electrical ratings against alternatives. Verify that substitute parts meet AEC-Q101 if automotive use is required. Ensure equivalent transition frequency and power dissipation capabilities to maintain performance integrity.
