Single Bipolar Transistors Procurement Notes

Verify the manufacturer designation as onsemi or Fairchild, as both entities have produced this part number. Confirm the specific suffix D74Z corresponds to the intended packaging and compliance status. Ensure the component matches the TO-92 form factor and NPN polarity required for the design. Cross-reference datasheets for exact hFE ranges and thermal limits before integration.

Single Bipolar Transistors Selection Notes

Select this component when high current drive is needed from a low input signal. The 1.2 A rating supports moderate load switching. The 30 V breakdown voltage suits low-voltage applications. Consider the TO-92 package constraints for board space and thermal dissipation requirements relative to the 625 mW power handling typical for this class.

Single Bipolar Transistors Part Context

This part belongs to the BC517 series of NPN Darlington transistors. It shares the core BC517 architecture but includes the D74Z suffix indicating specific manufacturing lot or packaging variations. Similar parts in the database include BC517 variants from other manufacturers like Texas Instruments and Fairchild, maintaining consistent electrical profiles.
