S8550-D-BP

Single Bipolar Transistors Overview

The S8550-D-BP is a PNP silicon small signal transistor manufactured by Micro Commercial Components (MCC). It is housed in a TO-92 plastic package and complies with RoHS standards. The device supports a maximum collector current of 0.5 A and a collector-emitter voltage of 25 V. Key electrical characteristics include a minimum DC current gain (hFE) of 160 and a maximum collector-base voltage of 40 V. It operates within a junction temperature range of -55 °C to +150 °C and offers power dissipation capabilities up to 0.625 W at 25 °C ambient temperature.

Single Bipolar Transistors Procurement Notes

Verify the specific suffix 'D' corresponds to the required hFE binning, as it indicates a minimum gain of 160. Confirm the TO-92 package orientation matches the target PCB footprint. Ensure the procurement documentation explicitly states RoHS compliance for the 'BP' suffix. Cross-reference the manufacturer's latest datasheet to validate absolute maximum ratings against the application's peak stress conditions.

Single Bipolar Transistors Selection Notes

Select this component when a PNP transistor with moderate current handling and high gain is required. The 'D' suffix ensures sufficient amplification for low-input signals. Consider the TO-92 package constraints for thermal management in enclosed designs. Verify that the 25 V collector-emitter rating exceeds the circuit's maximum supply voltage to prevent breakdown during operation.

Single Bipolar Transistors Part Context

This part belongs to the S8550 series of PNP transistors from MCC. It serves as a complementary counterpart to NPN types like the S8050. The series is designed for general-purpose applications requiring reliable performance in consumer electronics and industrial control systems. The TO-92 package provides a cost-effective solution for through-hole mounting.

Single Bipolar Transistors Replacement Considerations

Compatible substitutes include the S8550D from other manufacturers such as Slkor, provided the pinout and electrical parameters match. Verify that alternative parts meet the same 0.5 A current and 25 V voltage ratings. Ensure the replacement maintains the TO-92 package form factor for direct board compatibility.
