BC32840TA

Single Bipolar Transistors Overview

The BC32840TA is a PNP epitaxial silicon small-signal transistor manufactured by Fairchild Semiconductor. It features a maximum collector current of 800 mA and a collector-emitter breakdown voltage of 25 V. The device has a maximum power dissipation of 625 mW and operates within a temperature range up to 150 °C. Packaged in a TO-92-3 through-hole configuration, it is designed for switching and amplifier applications.

Single Bipolar Transistors Feature Summary

• PNP polarity construction using epitaxial silicon technology
• Suitable for general-purpose switching and linear amplifier circuits
• Through-hole mounting via standard TO-92-3 leaded package

Single Bipolar Transistors Applications

• General-purpose signal amplification
• Low-power switching circuits
• Driver stages for larger output devices

Single Bipolar Transistors Procurement Notes

Verify component authenticity as the BC32840TA is marked obsolete and not in production by Fairchild Semiconductor. Sourcing may involve surplus or secondary market channels. Confirm datasheet revisions and specific lot codes upon acquisition to ensure compliance with original specifications.

Single Bipolar Transistors Selection Notes

Select this component for low-voltage PNP applications requiring moderate current handling. Ensure the design accounts for the 25 V breakdown limit and 625 mW thermal constraints. Verify that the TO-92-3 package fits the target PCB layout and that no active replacement from the manufacturer is available.

Single Bipolar Transistors Part Context

This part belongs to the BC328 series of PNP transistors. It shares similar electrical characteristics with variants such as the BC328A but differs in specific grading or packaging suffixes. The series is widely recognized for use in consumer electronics and industrial control boards where small-signal PNP functionality is required.

Single Bipolar Transistors Replacement Considerations

Public confirmed substitute part numbers are not provided in the source documentation. As the component is obsolete, cross-reference with onsemi or other manufacturers for equivalent PNP TO-92 transistors with matching 25V/800mA ratings.
