BC547B,116

Single Bipolar Transistors Overview

The BC547B,116 is an NPN general-purpose silicon small-signal transistor manufactured by NXP Semiconductors. It is housed in a TO-92 (SOT54) plastic package with three leads. The device features a maximum collector current of 100 mA and a collector-emitter voltage rating of 45 V. As a 'B' grade variant, it specifies a minimum DC current gain (hFE) of 200, distinguishing it from lower-gain counterparts within the series.

Single Bipolar Transistors Feature Summary

• NPN silicon epitaxial planar construction for reliable switching and amplification
• Low current operation capability suitable for signal processing tasks
• Defined hFE binning ensures consistent amplification performance across units

Single Bipolar Transistors Applications

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

Single Bipolar Transistors Procurement Notes

Verify the suffix '116' corresponds to the specific tape-and-reel packaging configuration required for automated assembly. Confirm that the 'B' grading aligns with the necessary minimum gain specifications for the target design. Ensure the TO-92 package dimensions match the PCB footprint constraints. Cross-reference the manufacturer date code to ensure compliance with current environmental directives.

Single Bipolar Transistors Selection Notes

Select this component when a moderate current gain is required for general-purpose NPN applications. The BC547B offers higher gain than the standard BC547A, making it suitable for low-noise amplification where precise biasing is critical. Consider the thermal dissipation limits of the TO-92 package for high-power scenarios. Evaluate the 45V breakdown voltage against the maximum circuit supply rails to prevent overstress.

Single Bipolar Transistors Part Context

This component belongs to the BC547 family of NPN general-purpose transistors produced by NXP Semiconductors. The family includes variants with different gain characteristics, such as the BC547A and BC547C. These devices are widely used in consumer electronics and industrial control systems due to their versatility and standardized TO-92 packaging.

Single Bipolar Transistors Replacement Considerations

Compatible substitutes include the BC547B from other manufacturers such as ON Semiconductor or Diotec, provided they meet the same electrical parameters and package outline. Verify pinout compatibility and thermal characteristics before substitution.
