Single Bipolar Transistors Procurement Notes

Verify the specific datasheet revision and binning configuration (D suffix) required for your design. Confirm that the TO-92 package dimensions match your PCB footprint constraints. Ensure the supplier provides documentation confirming RoHS compliance status for the AP suffix variant prior to final procurement authorization.

Single Bipolar Transistors Selection Notes

Select this component when a PNP transistor with 1.5A continuous collector current capability is needed in a through-hole TO-92 package. Consider the 25V V(BR)CEO limit for circuit voltage headroom. Evaluate thermal management requirements as the 625mW dissipation rating applies at 25°C ambient conditions.

Single Bipolar Transistors Part Context

This part belongs to the S8550 series of PNP transistors manufactured by Micro Commercial Components. The series typically pairs with NPN counterparts like the S8050. The 'D' indicates a specific hFE binning grade, while 'AP' denotes environmental compliance. It serves as a standard discrete semiconductor solution for basic analog and digital logic interfacing tasks.

Single Bipolar Transistors Replacement Considerations

Cross-reference with other manufacturers offering PNP TO-92 transistors rated for 1.5A and 25V. Verify pinout compatibility (Emitter, Base, Collector) and ensure equivalent hFE characteristics are available in the replacement part's datasheet.
