NSBC143TDXV6T5G

Overview

The NSBC143TDXV6T5G is a dual digital transistor from onsemi, featuring one NPN and one PNP biased resistor transistor (BRT) array in a SOT-563 surface-mount package. It supports a collector-emitter voltage of 50 V and a continuous collector current of 100 mA. The device includes internal base resistors, typically 4.7 kOhms, to simplify circuit design. With a power dissipation rating of 357 mW and an operating temperature range from -55°C to +150°C, it is designed for high-density applications requiring compact switching solutions.

Feature Summary

• Integrates complementary NPN and PNP transistors with built-in biasing resistors into a single compact package.
• Eliminates the need for external discrete resistors, reducing component count and PCB footprint.
• Provides consistent electrical characteristics due to monolithic integration of transistors and resistors.

Applications

• General-purpose switching circuits in consumer electronics.
• Driver interfaces for logic level translation between microcontrollers and peripheral devices.
• Load switching applications in portable battery-powered equipment.

Procurement Notes

Verify the specific suffix 'G' indicates RoHS compliance and halogen-free status as per manufacturer standards. Confirm availability status, as some listings indicate this part may be discontinued or have limited stock. Check lead times carefully due to reported long delivery periods. Ensure the ordering quantity matches the reel packaging requirements if purchasing in bulk quantities.

Selection Notes

Select this component when a complementary pair of NPN and PNP switches is required in a minimal footprint. The 50 V rating suits low-voltage digital logic systems. Verify that the internal base resistance values align with the driving source capabilities. Consider thermal constraints given the 357 mW power dissipation limit in the small SOT-563 package.

Part Context

This part belongs to onsemi's NSBC series of dual BRTs, which combines NPN and PNP functions. It shares the SOT-563 form factor with other high-density transistor arrays. The 'T5G' suffix typically denotes tape and reel packaging with green/RoHS compliance. It serves as a space-saving alternative to discrete resistor-transistor combinations in modern compact designs.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Users should consult official cross-reference tools or datasheets for equivalent dual BRTs in SOT-563 packages with matching 50V/100mA ratings.
