Procurement Notes

Verify the authenticity of the DTA143ZUAHE3-TP by purchasing only from authorized MCC distributors or directly from Micro Commercial Components Corp. Products acquired from unauthorized sources lack full traceability and do not meet MCC quality standards for handling and storage. MCC does not provide warranty coverage for parts sourced outside its authorized network. Ensure documentation confirms the HE3 suffix indicates RoHS compliance and halogen-free status as defined in the official ordering information.

Selection Notes

Select the DTA143ZUAHE3-TP when a PNP digital transistor with integrated biasing is required for space-constrained designs using the SOT-323 package. The 4.7 kOhm input resistor simplifies circuit design by reducing component count. Consider this part for applications demanding high-frequency operation up to 250 MHz and robust thermal performance within a -55°C to +150°C range. The AEC-Q101 qualification makes it suitable for automotive environments where reliability under varying thermal conditions is critical.

Part Context

This component belongs to the DTA143ZUA series of digital transistors produced by Micro Commercial Components. The HE3 suffix specifically denotes a halogen-free, RoHS-compliant variant designed for environmentally conscious manufacturing. As a single PNP configuration device, it integrates both the transistor and bias resistors into one compact SOT-323 footprint, distinguishing it from standard bipolar junction transistors that require external base resistors for proper biasing.
