Single Bipolar Transistors Procurement Notes

Verify the specific suffix 'BU' against the official onsemi datasheet to confirm binning or gain classification, as this may differ from standard variants. Confirm component availability status, as distribution channels frequently list this part as obsolete or end-of-life. Ensure the ordering information matches the exact manufacturer part number to avoid receiving incorrect gain bins or packages.

Single Bipolar Transistors Selection Notes

Select this component when a small-signal NPN transistor with moderate speed and low current handling is required. The 25 V rating suits low-voltage logic interfaces. Compare the 100 mA limit against load requirements. Verify that the TO-92-3 package fits the PCB layout constraints. Consider thermal management for the 500 mW dissipation limit in enclosed designs.

Single Bipolar Transistors Part Context

This component belongs to the BC238 family of general-purpose NPN transistors produced by onsemi. The family typically includes variants differentiated by DC current gain (hFE) bins. The BC238 series is widely used in consumer electronics and industrial control boards for basic switching and amplification tasks within low-power environments.
