BC547CTF

Single Bipolar Transistors Overview

The BC547CTF is an NPN epitaxial silicon transistor from the BC547 series, manufactured by onsemi. It features a collector-emitter voltage (VCEO) of 45 V and a collector-base voltage (VCBO) of 50 V. The device supports a maximum DC collector current of 100 mA with a power dissipation rating of 500 mW. It offers a current gain bandwidth product (fT) of 300 MHz and a minimum DC current gain (hFE) of 420 in the C classification. The component is housed in a TO-92-3 package with kinked leads and is supplied in tape and reel packaging.

Single Bipolar Transistors Procurement Notes

Verify the part number against official onsemi documentation to ensure authenticity. Confirm that the ordering suffix matches the required packing method, as system integrations may alter nomenclature. Check for compliance with RoHS standards and confirm the specific hFE binning class required for your circuit design before finalizing procurement.

Single Bipolar Transistors Selection Notes

Select this component when a high-gain NPN transistor is needed for low-power amplification or switching tasks. Ensure the application voltage does not exceed the 45 V collector-emitter limit. Consider the thermal management requirements given the 500 mW power dissipation rating and verify that the TO-92 package fits the available board space.

Single Bipolar Transistors Part Context

This part belongs to the BC546/BC547/BC548/BC549/BC550 family of NPN epitaxial silicon transistors originally developed by Fairchild Semiconductor and now managed by onsemi. The BC547 variant specifically provides a 45 V breakdown voltage, distinguishing it from the higher-voltage BC546 and lower-voltage BC548 models within the same lineup.

Single Bipolar Transistors Replacement Considerations

The BC547BTF serves as a direct functional replacement offering identical electrical specifications but utilizes bulk packaging instead of tape and reel. Other variants like BC547CTA provide the same electrical profile in ammo pack format.
