8550SS-D-BP

Single Bipolar Transistors Overview

The S8550D-BP is a PNP silicon small-signal transistor manufactured by Micro Commercial Components (MCC). It features a maximum collector current of 0.5 A and a collector-emitter breakdown voltage of 25 V. The device is housed in a TO-92 plastic package with three leads. It supports a power dissipation of 0.625 W at 25°C ambient temperature and operates within a junction temperature range of -55°C to +150°C. The component complies with RoHS standards and carries the e3 lead-free finish designation.

• Lead-free finish compliant with RoHS directives
• High thermal stability supporting operation up to 150°C junction temperature

Single Bipolar Transistors Applications

• General-purpose signal amplification circuits
• Low-power switching applications
• Driver stages for logic interfaces

Single Bipolar Transistors Procurement Notes

Verify the specific suffix 'D' against official MCC documentation to confirm the DC current gain binning, as variants like 'B' or 'C' may exhibit different hFE ranges. Ensure the ordering code matches the exact package style and compliance markings required for the target assembly process. Cross-reference the datasheet revision date to validate electrical characteristics before finalizing procurement specifications.

Single Bipolar Transistors Selection Notes

Select this component when a PNP transistor with a 0.5 A continuous collector current limit is required in a through-hole TO-92 package. The 25 V collector-emitter voltage rating suits low-voltage digital and analog control loops. Consider the 0.625 W power dissipation capability relative to the expected thermal environment and heat sinking constraints during circuit design.

Single Bipolar Transistors Part Context

This part belongs to the S8550 series of PNP bipolar junction transistors produced by Micro Commercial Components. The series includes variants differentiated by gain bins and packaging styles, such as surface-mount options like MMSS8550. The S8550D-BP specifically denotes the through-hole TO-92 version with defined gain characteristics and RoHS compliance.

Single Bipolar Transistors Replacement Considerations

Compatible substitutes include other manufacturers' S8550 equivalents in TO-92 packages, provided they meet the 0.5 A current and 25 V voltage ratings. Surface-mount replacements require pin-compatible packages like SOT-23, though electrical parameters must be verified for equivalence.
