NSBA144EDXV6T1G

Overview

The NSBA144EDXV6T1G is a dual pre-biased NPN bipolar junction transistor array manufactured by ON Semiconductor, formerly Fairchild Semiconductor. It integrates two NPN transistors with built-in bias resistors in a compact SOT-563 surface-mount package. The device features a collector-emitter breakdown voltage of 50 V and a maximum continuous collector current of 100 mA per element. Each transistor includes an internal bias resistor network with a fixed ratio of 1:1. The component is lead-free compliant and housed in a six-terminal plastic outline package designed for automated surface-mount assembly.

Feature Summary

• Integrates two independent NPN transistors with built-in bias resistors to reduce external component count
• Fixed 1:1 bias resistor ratio simplifies circuit design and ensures consistent switching performance
• Compact SOT-563 package enables high-density PCB layouts and automated surface-mount processing

Applications

• General-purpose switching applications requiring dual isolated control signals
• Interface circuits replacing discrete transistor and resistor networks
• Digital logic level shifting and buffer stages in consumer electronics

Procurement Notes

Verify the manufacturer designation carefully, as ON Semiconductor acquired Fairchild Semiconductor's discrete product line. Ensure the ordering suffix matches the required tape-and-reel quantity. Confirm RoHS compliance status through the official datasheet rather than relying on legacy branding. Cross-reference the part number with current ON Semiconductor catalogs to confirm availability and revision status.

Selection Notes

Select this component when a dual NPN configuration with integrated biasing is required. The 50 V rating suits low-voltage digital systems. Verify that the 100 mA current limit meets load requirements. Consider thermal dissipation capabilities within the SOT-563 package for power constraints. Compare against single-transistor alternatives if only one channel is needed to optimize board space.

Part Context

This part belongs to the NSBA series of pre-biased transistor arrays from ON Semiconductor. It serves as a direct successor to legacy Fairchild Semiconductor discrete components. The series standardizes dual-transistor solutions with integrated biasing for simplified schematic design. It replaces multiple discrete components including transistors and base resistors in traditional designs.

Replacement Considerations

NSBA144EDXV6T5G shares identical electrical specifications and pinout configuration. Both parts utilize the SOT-563 package and feature dual NPN pre-biased structures. Verify packaging variations between tape-and-reel options before substitution.
