PN2222A APM TIN/LEAD

Single Bipolar Transistors Overview

The PN2222A APM TIN/LEAD is an NPN silicon general-purpose transistor manufactured by Central Semiconductor Corp. It features a TO-92-3 through-hole package with tin/lead terminations. Key electrical parameters include a collector-emitter voltage (VCEO) of 40 V, a collector-base voltage (VCBO) of 75 V, and an emitter-base voltage (VEBO) of 6 V. The device supports a maximum DC collector current of 600 mA and a power dissipation (Pd) of 500 mW. It offers a minimum DC current gain (hFE) of 100 and a transition frequency (fT) of 270 MHz. The operating temperature range spans from -65°C to +150°C.

Single Bipolar Transistors Feature Summary

• NPN silicon construction for general-purpose amplification and switching applications
• Through-hole TO-92-3 package configuration suitable for standard PCB mounting
• High thermal stability with a maximum junction temperature rating of 150°C

Single Bipolar Transistors Applications

• General-purpose signal amplification circuits
• Low-power switching applications in consumer electronics
• Driver stages for relays or indicator loads

Single Bipolar Transistors Procurement Notes

Verify the specific suffix 'APM TIN/LEAD' against the manufacturer's official datasheet to confirm terminal plating composition and packaging format. Ensure the ordering code matches the exact Central Semiconductor Corp part number to avoid confusion with lead-free or alternative package variants. Confirm RoHS compliance status if required by your assembly process, as tin/lead finishes may not meet all environmental directives.

Single Bipolar Transistors Selection Notes

Select this component when a robust NPN transistor with 40 V VCEO and 600 mA IC capability is required in a through-hole form factor. The 500 mW power dissipation rating makes it suitable for low-to-medium power tasks. Compare hFE ranges and fT specifications against circuit requirements to ensure adequate gain and speed performance for the intended frequency range.

Single Bipolar Transistors Part Context

This part belongs to the widely recognized PN2222A family of NPN small-signal transistors. While the base PN2222A designation is common across multiple manufacturers, the Central Semiconductor variant specifies particular electrical tolerances and physical attributes. The 'APM TIN/LEAD' suffix indicates specific termination and packaging details distinct from standard lead-free versions.

Single Bipolar Transistors Replacement Considerations

Direct substitutes include the 2N2222A and MPS-A56 from other manufacturers, provided they meet the same voltage, current, and package constraints. Verify that replacement parts offer equivalent hFE grades and thermal characteristics to maintain circuit performance without modification.
