BC547BTF

Single Bipolar Transistors Overview

The BC547BTF is an NPN epitaxial silicon transistor manufactured by ON Semiconductor. It features a collector-emitter voltage of 45 V, a maximum DC collector current of 100 mA, and a power dissipation rating of 500 mW. The device belongs to the B classification with a minimum DC current gain (hFE) of 200 at 2 mA. It utilizes a TO-92 package with straight leads and is supplied in tape and reel format.

Single Bipolar Transistors Feature Summary

• NPN epitaxial silicon construction for switching and amplifier applications
• High-voltage capability with 45 V collector-emitter breakdown
• Class B hFE grading ensuring a minimum gain of 200
• Low noise figure suitable for general-purpose signal processing

Single Bipolar Transistors Applications

• General purpose switching circuits
• Small signal amplification stages
• Audio pre-amplifier designs

Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix 'TF' corresponds to the tape and reel packing method rather than bulk or ammo packaging. Confirm that the component meets RoHS3 compliance standards as indicated in the manufacturer documentation. Ensure the part number matches the updated nomenclature following the Fairchild Semiconductor integration into ON Semiconductor systems.

Single Bipolar Transistors Selection Notes

Select this component when a moderate current gain of at least 200 is required alongside standard 45 V operation. The tape and reel configuration supports automated surface mount or through-hole assembly processes. Consider the thermal characteristics and power dissipation limits relative to the expected operating temperature range of the target application environment.

Single Bipolar Transistors Part Context

This component is part of the BC546/BC547/BC548/BC549/BC550 family of NPN epitaxial silicon transistors originally developed by Fairchild Semiconductor. Following corporate integration, these devices are now managed under the ON Semiconductor portfolio. The BC547 variant specifically provides a balanced performance profile between voltage handling and current gain for versatile electronic circuit implementations.

Single Bipolar Transistors Replacement Considerations

Compatible substitutes include BC547BTA and BC547BBU from the same manufacturer series. Verify pinout compatibility and electrical specifications before substituting components from other manufacturers.
