PDTA123EMB,315

Overview

The PDTA123EMB,315 is a PNP resistor-equipped transistor from the Nexperia PDTA123E series. It integrates a single NPN structure with built-in bias resistors (R1 = 2.2 kΩ, R2 = 2.2 kΩ) to simplify circuit design and reduce component count. The device operates with a maximum collector-emitter voltage of 50 V and a continuous collector current of 100 mA. It is housed in a DFN1006B-3 package (SOT883B) with dimensions of 1 x 0.6 x 0.37 mm. The component supports a maximum junction temperature of 150 °C and has a total power dissipation of 250 mW. It is qualified under AEC-Q101 standards for automotive applications.

Feature Summary

• Integrates PNP transistor with dual bias resistors for simplified circuit topology
• Automotive-grade qualification compliant with AEC-Q101 standards
• Compact surface-mount packaging designed for automated pick-and-place assembly

Applications

• General purpose switching and amplification circuits
• Inverter and interface logic circuits
• Low-power circuit driver stages

Procurement Notes

Verify the complete part number including the suffix against official Nexperia documentation to ensure correct packaging configuration. Confirm that the specific reel or cut-tape format matches production requirements. Cross-reference the AEC-Q101 qualification status if the application demands strict automotive reliability standards. Ensure compatibility with standard reflow soldering profiles for the DFN1006B-3 package.

Selection Notes

Select this component when space constraints require a compact SMD solution for PNP switching tasks. The integrated resistor network eliminates external bias components, reducing board area and assembly costs. Verify that the 50 V rating and 100 mA current capacity meet the specific load requirements. Consider the thermal performance within the small footprint for high-density designs.

Part Context

This part belongs to the PDTA123E series of PNP resistor-equipped transistors. It shares electrical characteristics with other variants in the series but differs in physical package and automotive qualification. The DFN1006B-3 package offers a smaller profile compared to standard SOT23 versions, facilitating use in thin electronic devices.

Replacement Considerations

Direct substitutes include other PDTA123E series variants such as PDTA123EM or PDTA123EU, provided the package footprint and lead pitch are compatible with the existing PCB layout. Verify that alternative packages maintain the required 50 V and 100 mA ratings.
