PBLS2021D,115

Overview

The PBLS2021D,115 is a digital transistor array manufactured by Nexperia USA Inc., featuring one NPN and one PNP pre-biased bipolar junction transistor (BJT) in a single surface-mount package. The device integrates internal base resistors to simplify circuit design and reduce component count. It operates within a temperature range of -65°C to +150°C and is housed in an SOT-363 (SC-88) or 6-TSSOP compatible footprint. Key electrical specifications include a collector-emitter breakdown voltage of 50V for the NPN and 40V for the PNP, with continuous collector currents rated at 100mA and 500mA respectively. The unit offers a maximum power dissipation of 300mW and a transition frequency of 300MHz, ensuring reliable performance in high-density applications.

Feature Summary

• Dual configuration combining one NPN and one PNP pre-biased transistor for space-efficient designs
• Integrated base resistors eliminate external biasing components, reducing board area and assembly complexity
• High thermal stability supporting operation up to 150°C ambient temperature
• Low saturation voltage characteristics for efficient switching performance

Applications

• General-purpose switching circuits requiring complementary NPN/PNP pairs
• Level shifting interfaces between different logic families
• Driver stages for low-power loads in consumer electronics
• Battery management systems utilizing compact dual-transistor solutions

Procurement Notes

Verify the specific suffix and packaging variant when ordering, as availability may vary between cut tape, reel, or Digi-Reel formats. Confirm RoHS compliance status and moisture sensitivity level requirements against your manufacturing process standards. Ensure the selected distributor provides traceable documentation matching the Nexperia official part number PBLS2021D,115 to avoid counterfeit risks.

Selection Notes

Select this component when a compact solution for simultaneous NPN and PNP switching is required without external biasing networks. Compare the 100mA/500mA current ratings against load requirements to ensure adequate margin. Consider the SOT-363 package dimensions for PCB layout constraints relative to alternative discrete transistor arrangements or other digital transistor arrays in the Nexperia portfolio.

Part Context

This part belongs to Nexperia's extensive portfolio of digital transistors, which are designed to replace multiple discrete components with single integrated packages. The PBLS series specifically targets applications needing complementary switching capabilities in minimal footprints. These devices are widely used in portable electronics and industrial control panels where space optimization and simplified bill of materials are critical design drivers.

Replacement Considerations

Check for direct substitutes within the PBLS family such as PBLS2022D or PBLS2023D if current ratings differ. Verify pinout compatibility with existing PCB layouts before substituting with similar offerings from other manufacturers like ON Semiconductor or Rohm.
