Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix 'ATA' corresponds to the Ammo Pack packaging method when sourcing components. Confirm that the part number reflects the transition from Fairchild Semiconductor nomenclature to ON Semiconductor standards, ensuring compatibility with system requirements. Validate authenticity through authorized distributors to mitigate counterfeiting risks associated with legacy semiconductor parts.

Single Bipolar Transistors Selection Notes

Select this component for designs requiring a robust NPN transistor with moderate current handling capabilities. The TO-92 package facilitates easy integration into through-hole PCB layouts. Ensure thermal management aligns with the specified 625 mW dissipation limit and derating curves. Consider the 40V breakdown voltage and 300MHz bandwidth when evaluating suitability for high-frequency or higher-voltage circuit topologies.

Single Bipolar Transistors Part Context

This component belongs to the PN2222A series of NPN general-purpose transistors. Originally developed by Fairchild Semiconductor, the product line was integrated into ON Semiconductor's portfolio following corporate acquisition. The PN2222ATA variant specifically denotes the ammo pack packaging format, distinguishing it from bulk or tape-and-reel configurations within the same electrical specification family.

Single Bipolar Transistors Replacement Considerations

Equivalent alternatives include the MPS2222AG and KSP2222ATA, which share similar electrical characteristics and package types. Verify pinout compatibility and thermal resistance specifications before substitution. Note that some legacy part numbers may require verification against updated ON Semiconductor ordering information due to historical naming conventions.
