Procurement Notes

Verify component authenticity by purchasing exclusively from authorized MCC distributors or directly from the manufacturer. Ensure the ordering suffix matches the required specifications, as it indicates compliance attributes such as RoHS status. Confirm that the specific part number corresponds to the intended application requirements before finalizing procurement orders.

Selection Notes

Select this component when a PNP digital transistor with integrated biasing is required for space-constrained designs. The SOT-323 package offers a compact footprint suitable for high-density PCB layouts. Consider the -50 V voltage rating and -100 mA current capability to ensure adequate headroom for the target switching or logic interface application.

Part Context

This part belongs to the DTA143 series of pre-biased transistors from Micro Commercial Components. It is designed to replace discrete resistor-transistor combinations, reducing board space and assembly costs. The 'HE3' suffix typically denotes specific packaging or environmental compliance variations within the product line.

Replacement Considerations

Direct substitutes must match the PNP polarity, SOT-323 package, and similar electrical ratings. Verify compatibility with existing circuit designs, particularly regarding the internal resistor values and current gain characteristics, before implementing any alternative components.
