BC557C-AP

Single Bipolar Transistors Overview

The BC557C-AP is a PNP general-purpose bipolar junction transistor manufactured by Micro Commercial Components. It utilizes a TO-92 plastic package and is designed for low current and low voltage applications. The device features a maximum collector current of 100 mA, a collector-emitter voltage of 45 V, and a collector-base voltage of 50 V. It offers a DC current gain range of 200 to 450, ensuring consistent performance for switching and amplification tasks within an operating temperature range of -55°C to +150°C.

Single Bipolar Transistors Feature Summary

• PNP silicon epitaxial planar construction for reliable operation
• High DC current gain classification (C suffix) for precise amplification
• Designed for general-purpose switching and linear amplification

Single Bipolar Transistors Applications

• General purpose switching circuits
• Linear amplification stages
• Driver transistors in audio or signal processing

Single Bipolar Transistors Procurement Notes

Verify the specific manufacturer source, as MCC may distribute components originally specified by other semiconductor manufacturers such as NXP. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability for this specific suffix can vary. Ensure the ordering information matches the required gain binning for your circuit design.

Single Bipolar Transistors Selection Notes

Select this component when a PNP transistor with high current gain (200-450) is required for low-power applications. It serves as the complement to the BC547C NPN transistor. Consider thermal management if operating near the maximum power dissipation limit of 625 mW. Verify that the TO-92 package fits the mechanical constraints of the target PCB layout.

Single Bipolar Transistors Part Context

This part belongs to the widely used BC557 series of PNP general-purpose transistors. The 'C' suffix indicates a specific binning for higher DC current gain compared to A or B variants. These transistors are standard replacements in legacy designs and consumer electronics, offering a balance of performance and cost-effectiveness for small-signal applications.

Single Bipolar Transistors Replacement Considerations

Compatible substitutes include BC557B, BC557A, and generic equivalents like 2SB733 or SS8550, provided the gain requirements and voltage ratings align with the circuit design.
