Single Bipolar Transistors Procurement Notes

Verify the specific suffix 'CTAR' against the manufacturer's official documentation to confirm tape-and-reel packaging specifications. Ensure the hFE gain bin corresponds to the C grade (minimum 420) required by the circuit design. Cross-reference the RoHS status and SVHC declarations with the latest compliance certificates provided by onsemi before final procurement.

Single Bipolar Transistors Selection Notes

Select this component when a high-gain NPN transistor is required for low-power applications. The C-grade binning ensures a minimum DC current gain of 420, distinguishing it from lower gain variants. Verify that the 30V voltage rating and 100mA current limit align with the load requirements. Consider the complementary BC558CTAR for push-pull configurations requiring matched PNP characteristics.

Single Bipolar Transistors Part Context

This part belongs to the widely used BC546–BC550 series of NPN transistors. These devices are standard components in electronic design, offering a balance of performance and cost-effectiveness. The BC548 variant specifically targets applications requiring moderate voltage handling and reliable amplification in compact through-hole assemblies.

Single Bipolar Transistors Replacement Considerations

Compatible substitutes include BC548C from other manufacturers such as Fairchild or Diotec, provided they meet the same 30V/100mA/TO-92 specifications. Ensure any replacement maintains the C-grade hFE minimum of 420.
