Single Bipolar Transistors Procurement Notes

Verify the manufacturer marking and date code against official onsemi documentation to confirm authenticity. Ensure the ordering suffix matches the specific tape-and-reel or bulk packaging requirements for your assembly line. Cross-reference the JEDEC-95 code TO-92 to guarantee mechanical compatibility with existing PCB footprints and automated placement equipment specifications.

Single Bipolar Transistors Selection Notes

Select this component when a PNP transistor with a 30V breakdown voltage and 100mA current capacity is required. The BC558B variant offers a guaranteed minimum hFE of 75, providing consistent gain for linear applications. Consider the TO-92 package constraints for thermal dissipation and board space limitations compared to surface-mount alternatives.

Single Bipolar Transistors Part Context

This part belongs to the BC558 series of PNP transistors, widely used in consumer electronics and industrial control systems. The J35Z suffix typically denotes specific packaging or lot traceability details defined by onsemi. It serves as a complementary device to NPN counterparts like the BC548 in push-pull configurations.

Single Bipolar Transistors Replacement Considerations

Direct substitutes include the BC558B from other manufacturers such as STMicroelectronics or Diodes Inc., provided they meet the same 30V, 100mA, and TO-92 package specifications. Verify pinout compatibility and hFE binning before substitution.
