PN2222-L-AP

Single Bipolar Transistors Overview

The PN2222-L-AP is an NPN small-signal bipolar junction transistor manufactured by Micro Commercial Components. It utilizes silicon technology and is housed in a TO-92 (TO-226AA) through-hole package. Key electrical ratings include a maximum collector-emitter voltage of 30V, a maximum DC collector current of 600mA, and a power dissipation capability of 625mW. The device features a transition frequency of 300MHz and operates within a temperature range of -55°C to +150°C.

Single Bipolar Transistors Feature Summary

• NPN polarity configuration for single transistor applications
• Silicon-based construction for reliable switching performance
• Through-hole mounting style compatible with standard PCB layouts

Single Bipolar Transistors Applications

• General-purpose signal amplification circuits
• Switching applications requiring moderate current handling
• Audio pre-amplifier stages

Single Bipolar Transistors Procurement Notes

Verify the specific suffix 'L' against official MCC documentation to confirm the 30V rating variant, as standard PN2222 parts often differ. Confirm RoHS compliance status directly with the manufacturer or authorized distributors, as legacy through-hole packages may have varying environmental declarations. Ensure the TO-92 lead form matches the target assembly requirements.

Single Bipolar Transistors Selection Notes

Select this component when a 30V collector-emitter voltage limit is required rather than the higher 40V found in other variants. The 625mW power dissipation rating supports higher thermal loads compared to surface-mount alternatives. Verify that the through-hole package fits the mechanical constraints of the design, as surface-mount equivalents like MMBT2222A offer different thermal profiles.

Single Bipolar Transistors Part Context

This part belongs to the widely used PN2222 family of NPN transistors, serving as a fundamental discrete semiconductor component. The 'L' suffix typically denotes specific voltage or packaging variations within the MCC portfolio. It is categorized under general-purpose bipolar junction transistors intended for low-power switching and amplification tasks in consumer and industrial electronics.

Single Bipolar Transistors Replacement Considerations

Standard PN2222 variants with 40V ratings may require circuit review due to voltage headroom differences. Surface-mount replacements such as MMBT2222A necessitate footprint changes. Verify thermal resistance characteristics when substituting with higher power dissipation devices.
