BC546CBU

Single Bipolar Transistors Overview

The BC546CBU is an NPN epitaxial silicon small-signal transistor manufactured by onsemi. It utilizes a TO-92 (TO-226AA) three-pin through-hole package. Key electrical ratings include a maximum collector current of 100 mA, a collector-emitter voltage of 65 V, and a collector-base voltage of 80 V. The device supports a maximum power dissipation of 500 mW and operates at junction temperatures up to 150°C. It features a minimum DC current gain (hFE) of 110 and a transition frequency of 300 MHz.

Single Bipolar Transistors Feature Summary

• High voltage capability with 65V collector-emitter breakdown for robust switching applications
• Low noise performance suitable for sensitive signal amplification circuits
• Complementary design within the BC546-BC550 series for flexible circuit implementation

Single Bipolar Transistors Applications

Single Bipolar Transistors Procurement Notes

Verify component authenticity against official onsemi datasheets due to widespread availability in the market. Confirm that the specific suffix matches the required hFE binning and packaging specifications. Check for RoHS compliance status as historical batches may vary. Ensure the supplier provides traceable documentation for quality assurance purposes prior to finalizing procurement orders.

Single Bipolar Transistors Selection Notes

Select this component when high voltage handling is required alongside standard small-signal amplification needs. The 65V rating distinguishes it from lower-voltage variants like the BC547 or BC548. Consider the complementary BC556 PNP counterpart for push-pull configurations. Evaluate thermal management requirements given the 500mW dissipation limit in the TO-92 package.

Single Bipolar Transistors Part Context

The BC546CBU belongs to the BC546-BC550 family of NPN transistors produced by onsemi. This series is widely recognized for its reliability in consumer electronics and industrial control systems. The BC546 variant specifically offers higher voltage tolerance compared to other members of the same family, making it distinct for medium-voltage applications.
