BC546-AP

Single Bipolar Transistors Overview

The BC546-AP is an NPN silicon small signal bipolar junction transistor manufactured by Micro Commercial Components. It features a maximum collector current of 100mA and a collector-emitter breakdown voltage of 65V. The device operates with a maximum power dissipation of 625mW and has a transition frequency of 300MHz. DC current gain (hFE) is specified at a minimum of 200 under standard test conditions. The component utilizes a TO-92 plastic package for through-hole mounting and supports a junction temperature range from -55°C to 150°C.

• Switching applications in low power electronics
• Audio signal processing stages

Single Bipolar Transistors Procurement Notes

Verify the specific suffix against official MCC documentation, as availability varies by manufacturer batch. Confirm RoHS compliance status directly with the supplier or datasheet, as historical data indicates potential variations in lead-free certification across different production runs. Ensure the TO-92 package dimensions match the target PCB footprint requirements before finalizing procurement decisions.

Single Bipolar Transistors Selection Notes

Select this component when a general-purpose NPN transistor with moderate voltage handling and defined current gain is required. The TO-92 package suits manual assembly or automated through-hole processes. Compare hFE binning requirements against circuit sensitivity, as the 'B' suffix typically denotes a specific gain range. Verify thermal management needs given the 625mW power dissipation limit in enclosed environments.

Single Bipolar Transistors Part Context

This part belongs to the BC546 series of NPN silicon transistors produced by Micro Commercial Components. It is functionally similar to industry-standard equivalents like the BC546B but may differ in specific electrical tolerances and packaging certifications. The series is widely used in consumer electronics and industrial control boards requiring reliable small-signal switching and amplification capabilities.

Single Bipolar Transistors Replacement Considerations

Cross-reference with BC546B variants from other manufacturers such as NXP or ON Semiconductor. Verify pinout compatibility and ensure that the replacement part meets or exceeds the 65V V(BR)CEO and 100mA Ic specifications. Check for any differences in hFE grading if the application requires tight gain control.
