Single Bipolar Transistors Procurement Notes

Verify the specific suffix ',126' against official NXP documentation to confirm reel packaging specifications or tape-and-reel quantities. Ensure the part number matches the exact electrical characteristics required for the design, particularly the hFE grading. Confirm RoHS compliance status as indicated in manufacturer datasheets prior to integration.

Single Bipolar Transistors Selection Notes

Select this component when a standard NPN transistor with high current gain is required for low-power signal processing. The TO-92 package is suitable for through-hole mounting on PCBs where space allows. Consider the 45 V voltage limit and 100 mA current capacity to ensure operation remains within safe limits for the intended circuit topology.

Single Bipolar Transistors Part Context

The BC547 series consists of NPN silicon transistors intended for general-purpose use. The 'C' suffix denotes a specific binning category for current gain, offering higher amplification than lower-grade variants. This family serves as a fundamental discrete semiconductor component in analog and digital logic circuits.

Single Bipolar Transistors Replacement Considerations

Official PNP complements include the BC556 and BC557. Cross-manufacturer equivalents such as the 2N3904 may be considered if electrical parameters align, though pinout and gain distributions should be verified against the specific application requirements.
