NSBC144EPDXV6T5

Overview

The NSBC144EPDXV6T5 is a dual bias resistor transistor (BRT) from onsemi, housed in an SOT-563 package. It integrates one NPN and one PNP silicon surface mount transistor with monolithic bias networks. Each BRT contains a series base resistor and a base-emitter resistor to replace discrete components. The device features a collector-emitter voltage of 50 Vdc and a continuous collector current of 100 mAdc. Total power dissipation reaches 500 mW when both junctions are heated. The typical input resistors R1 and R2 are both 47 kOhms.

Feature Summary

• Integrates complementary NPN and PNP transistors with built-in bias resistor networks into a single compact package
• Eliminates the need for external discrete biasing components to simplify circuit design
• Designed for low-power surface mount applications where board space is limited

Applications

• Low power surface mount applications requiring board space optimization
• Circuit designs needing integrated biasing for digital switching
• Complementary transistor arrays for signal processing or logic interfaces

Procurement Notes

Verify the specific ordering suffix T5 against official documentation to confirm the 2 mm pitch tape and reel configuration containing 8000 units per reel. Ensure compatibility with standard SMT assembly processes for the SOT-563 package. Confirm RoHS compliance status through the manufacturer's latest environmental declarations before finalizing procurement specifications.

Selection Notes

Select this component when a complementary NPN/PNP pair with identical 47 kOhm bias resistors is required. Verify that the 50 V collector-emitter voltage and 100 mA current ratings meet the application requirements. Consider the thermal resistance characteristics if multiple devices operate simultaneously within the same enclosure.

Part Context

This part belongs to the NSBC114EPDXV6 series of dual bias resistor transistors manufactured by onsemi. The series includes various resistor combinations within the same SOT-563 footprint. The T5 suffix specifically denotes the 2 mm pitch tape and reel packaging format, distinguishing it from the T1 variant which uses a 4 mm pitch.

Replacement Considerations

Direct substitutes include NSBC144EPDXV6T1G and NSBC144EPDXV6T1. Verify pinout compatibility and electrical parameters such as hFE and saturation voltage before substitution.
