Procurement Notes

Verify the specific datasheet version and packaging configuration before procurement, as availability may vary by region. Confirm that the SOT-523 package dimensions align with the target PCB footprint. Ensure compliance with relevant environmental standards such as RoHS if required by the end application. Cross-reference the manufacturer part number with authorized distributors to confirm authenticity and supply chain stability.

Selection Notes

Select this component when a compact NPN digital transistor with integrated biasing is required. The SOT-523 package offers a smaller footprint compared to standard SOT-23 options. Verify that the 50 V voltage rating and 100 mA current capacity meet the circuit requirements. Consider the 150 mW power dissipation limit when designing thermal management strategies for dense layouts.

Part Context

The DTA144VE-TP belongs to the DTA series of pre-biased transistors from Micro Commercial Components. This series typically includes various configurations of NPN and PNP devices with different resistor ratios. The VE suffix indicates specific internal resistor values and characteristics unique to this variant within the broader DTA product family.

Replacement Considerations

Compatible substitutes include other NPN pre-biased transistors in the SOT-523 package with similar electrical ratings. Verify equivalent resistor values and hFE ranges before substitution. Examples from other manufacturers may include parts from ON Semiconductor or Diodes Inc., provided they match the pinout and performance specifications.
