Procurement Notes

Verify the manufacturer origin, as Fairchild Semiconductor's discrete product line has been acquired by onsemi. Confirm that the specific part number corresponds to the original Fairchild datasheet specifications rather than the successor company's updated documentation or alternative sourcing channels.

Selection Notes

Select this component for designs requiring a 40V NPN transistor with general-purpose characteristics. Ensure the thermal management and current requirements align with the device's ratings. Verify package compatibility with the intended PCB footprint and soldering profile during the design phase.

Part Context

This component belongs to the family of small-signal NPN transistors used in consumer and industrial electronics. It serves as a fundamental active element for signal processing and power control tasks within larger circuit assemblies.

Replacement Considerations

Check for equivalents such as the BC547 series or other generic NPN transistors with matching VCEO and package dimensions. Verify pinout compatibility before substitution.
