BC547CTFR

Single Bipolar Transistors Overview

The BC547CTFR is an NPN epitaxial silicon transistor manufactured by onsemi. It features a collector-emitter voltage (VCEO) of 45 V and a maximum DC collector current (IC) of 100 mA. The device provides a minimum DC current gain (hFE) of 420, with a typical range up to 800 at IC = 2 mA and VCE = 5 V. It has a power dissipation rating of 500 mW and a transition frequency (fT) of 300 MHz. 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 specific suffix matches the required tape and reel packing method. Check for any updates regarding Fairchild Semiconductor integration nomenclature changes. Ensure compliance with RoHS directives if applicable to your manufacturing process. Validate all operating parameters for your specific application requirements before finalizing procurement.

Single Bipolar Transistors Selection Notes

Select this component when high DC current gain is required for low-current amplification tasks. The 45 V collector-emitter voltage rating makes it suitable for moderate voltage applications. Consider the TO-92 through-hole package for standard PCB layouts requiring kinked leads. Evaluate the 500 mW power dissipation limit against thermal management constraints in the target design environment.

Single Bipolar Transistors Part Context

This component belongs to the BC546/BC547/BC548/BC549/BC550 family of NPN epitaxial silicon transistors originally developed by Fairchild Semiconductor. Following the acquisition, these products are now managed under the onsemi portfolio. The BC547 variant specifically offers a 45 V breakdown voltage, distinguishing it from the higher voltage BC546 and lower voltage BC548 models within the same series.

Single Bipolar Transistors Replacement Considerations

Compatible substitutes include BC547BTF and BC547ATA, which share the same electrical specifications but differ in packaging methods such as bulk or ammo box formats.
