NSBC124XPDXV6T1G

Overview

The NSBC124XPDXV6T1G is a complementary Bias Resistor Transistor (BRT) from onsemi, integrating an NPN and a PNP transistor with monolithic bias resistor networks into a single SOT-563 package. It replaces discrete devices and external resistors to reduce board space and component count. The device features a maximum collector-emitter voltage of 50 Vdc and continuous collector current of 100 mAdc for both polarities. Electrical characteristics include a typical DC current gain of 150 at 5.0 mA and 10 V, and a collector-emitter saturation voltage of 0.25 Vdc max at 10 mA. Internal resistors are typically 22 kOhms and 47 kOhms with a ratio of 0.47. Thermal dissipation reaches 357 mW in the SOT-563 configuration.

Feature Summary

• Integrates dual NPN and PNP transistors with monolithic bias resistor networks
• Eliminates discrete components to simplify circuit design and reduce board space
• Complementary configuration supports versatile switching applications

Applications

• General-purpose switching circuits requiring compact form factors
• Driver stages for logic interfaces replacing discrete bias networks

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status and manufacturing site requirements if unique control changes apply. Ensure the selected variant matches the required thermal and electrical parameters for the target application environment.

Selection Notes

Select this component when a complementary pair of digital transistors is required in a minimal footprint. Compare the internal resistor values and ratios against standard discrete designs to ensure proper biasing. Evaluate the thermal resistance and power dissipation limits relative to the expected operating temperature range and duty cycle.

Part Context

This part belongs to the DTC124XP series of complementary Bias Resistor Transistors. It is functionally related to other BRTs in the family but distinguished by its specific resistor network values and SOT-563 packaging. The series is designed to streamline the integration of bipolar junction transistors in modern electronic systems.

Replacement Considerations

Direct substitutes include NSVMUN5334DW1T1G in the SOT-363 package. Verify pin compatibility and electrical ratings before substitution. Other complementary BRTs may require schematic adjustments due to differing internal resistor configurations.
