BC557C-BP

Single Bipolar Transistors Overview

The BC557C-BP is a PNP silicon planar epitaxial transistor manufactured by Micro Commercial Components (MCC). It belongs to the BC557 series and is housed in a TO-92 plastic package. Key electrical ratings include a collector-emitter voltage of -45V, a collector-base voltage of -50V, and an emitter-base voltage of -5V. The device supports a continuous collector current of 0.1A with a maximum power dissipation of 0.625W at 25°C ambient temperature. The 'C' suffix indicates a specific DC current gain binning range typical for this series variant.

Single Bipolar Transistors Procurement Notes

Verify component authenticity through official MCC documentation or authorized distributor channels. Confirm that the part number matches the exact suffix requirements for your design. Note that availability status may vary as distribution networks update their stock levels. Ensure compliance with relevant environmental directives such as RoHS before final integration into production assemblies.

Single Bipolar Transistors Selection Notes

Select this component when a PNP transistor with moderate voltage ratings and low current capacity is required. The TO-92 package facilitates through-hole mounting on printed circuit boards. Consider the specific hFE binning associated with the 'C' suffix if precise gain characteristics are critical for the amplifier stage design compared to other variants in the same family.

Single Bipolar Transistors Part Context

This component is part of the widely utilized BC557 series of bipolar junction transistors. The series includes multiple gain bins denoted by suffixes A, B, and C, allowing designers to select devices based on required amplification factors. The BC557C variant specifically targets applications needing higher minimum gain thresholds than the standard BC557B version while maintaining identical voltage and current ratings.

Single Bipolar Transistors Replacement Considerations

Compatible substitutes include BC557C from manufacturers such as NXP, Diodes Incorporated, and Fairchild Semiconductor. Ensure the replacement maintains the TO-92 package outline and identical pinout configuration. Verify that the alternative part meets the same -45V VCEO and 0.1A IC specifications.
