BC556C-AP

Single Bipolar Transistors Overview

The BC556C-AP is a PNP silicon general-purpose bipolar junction transistor manufactured by Micro Commercial Components. It is housed in a TO-92 plastic package with three pins. The device supports a maximum collector current of 100 mA and a collector-emitter voltage of 65 V. It features a minimum DC current gain (hFE) of 420, classifying it as a high-gain variant within the BC556 series.

Single Bipolar Transistors Feature Summary

• High DC current gain suitable for sensitive signal processing applications
• Low power consumption characteristics optimized for battery-operated circuits

Single Bipolar Transistors Applications

• General purpose switching circuits
• Audio frequency amplification stages
• Logic level interfacing and buffering

Single Bipolar Transistors Procurement Notes

Verify the specific manufacturer source, as the BC556 series is widely produced by multiple vendors including NXP and STMicroelectronics. Confirm that the datasheet specifications align with your design requirements, particularly regarding thermal resistance and pinout orientation in the TO-92 package. Ensure RoHS compliance documentation is available if required for your assembly process.

Single Bipolar Transistors Selection Notes

Select this component when a PNP transistor with moderate voltage handling and high current gain is required. The BC556C-AP serves as the complementary counterpart to the BC547C NPN transistor. Consider the TO-92 package constraints for thermal dissipation and board space. Verify that the 65V rating meets the circuit's peak voltage demands.

Single Bipolar Transistors Part Context

This component belongs to the standard BC546/BC547/BC548 and BC556/BC557/BC558 families of small-signal transistors. These devices are industry-standard replacements for older germanium or early silicon equivalents. The 'C' suffix typically denotes the highest binning for current gain within the family, ensuring consistent performance across production batches.

Single Bipolar Transistors Replacement Considerations

Direct functional substitutes include the BC556B-AP and generic BC556 parts from other manufacturers such as NXP or STMicroelectronics. Verify pin compatibility and hFE ranges before substitution.
