NSBA144TF3T5G

Overview

The NSBA144TF3T5G is a PNP Bias Resistor Transistor (BRT) from onsemi, integrating a single transistor with a monolithic bias network consisting of a series base resistor and a base-emitter resistor. It operates within a collector-emitter voltage range of 50 Vdc and supports continuous collector currents up to 100 mAdc. The device features a typical input resistance of 47 kOhms and maintains an operating temperature range from -55°C to +150°C. Packaged in the compact SOT-1123 form factor, it is supplied in tape and reel quantities of 8000 units.

Feature Summary

• Integrates a single PNP transistor with a monolithic bias network comprising two resistors to replace discrete components.
• Designed to simplify circuit design by eliminating external resistor bias networks.
• Reduces overall board space and component count in electronic assemblies.

Applications

• Replacing single devices and their associated external resistor bias networks
• Simplifying digital logic interface circuits
• Reducing bill-of-materials complexity in embedded systems

Procurement Notes

Verify the specific ordering suffix T5G confirms the SOT-1123 package and 8000-unit tape and reel shipping configuration. Confirm RoHS compliance and Pb-free status requirements against current project specifications. Ensure the manufacturer designation matches onsemi Semiconductor Components Industries, LLC for authenticity. Validate that the part marking corresponds to the specified device code for quality assurance purposes.

Selection Notes

Select this component when a compact PNP solution with integrated biasing is required. The SOT-1123 package offers significant space savings compared to larger transistor packages. Verify that the 47 kOhm internal resistance aligns with the target drive conditions. Consider the thermal dissipation limits relative to the ambient operating environment and PCB copper trace area available for heat spreading.

Part Context

This component belongs to the NSBA144TF3 series of digital transistors. It shares electrical characteristics with other variants in the DTA144T family but utilizes a distinct SOT-1123 package. The series is designed to provide equivalent functionality to discrete BJT configurations while minimizing footprint. Other package options for similar electrical parameters include SC-59, SOT-23, and SC-70.

Replacement Considerations

Direct substitutes include MUN2140T1G, MMUN2140LT1G, MUN5140T1G, DTA144TET1G, and DTA144TM3T5G. Note that these alternatives utilize different package styles such as SC-59, SOT-23, or SC-75. Verify pinout compatibility and physical dimensions before substituting to ensure mechanical fit within the existing layout.
