BC546A PBFREE

Single Bipolar Transistors Overview

The BC546A PBFREE is an NPN general-purpose small-signal bipolar junction transistor manufactured by Central Semiconductor. It utilizes a TO-92 through-hole package and is designed for amplifier and switching applications. The device features a maximum collector-emitter voltage of 65V, a continuous collector current of 100mA, and a power dissipation rating of 500mW. The 'A' suffix indicates a specific DC current gain (hFE) binning category within the product family, ensuring consistent amplification characteristics for precision circuit designs.

Single Bipolar Transistors Feature Summary

• NPN silicon construction optimized for low-noise general-purpose amplification
• Through-hole TO-92 package suitable for standard PCB mounting
• Defined hFE binning for predictable gain performance in linear circuits

Single Bipolar Transistors Applications

• General-purpose signal amplification stages
• Electronic switching circuits
• Audio pre-amplifier inputs

Single Bipolar Transistors Procurement Notes

Verify the exact datasheet revision and hFE binning specifications directly with Central Semiconductor or authorized distributors before integration. Confirm that the TO-92 lead form matches the target PCB footprint requirements. Ensure compliance with RoHS directives if required by the final assembly standards.

Single Bipolar Transistors Selection Notes

Select this component when a standard NPN transistor with 65V VCEO and 100mA IC capability is required. The BC546A variant offers tighter gain tolerances compared to standard grades, making it suitable for applications requiring consistent amplification factors without extensive manual sorting.

Single Bipolar Transistors Part Context

This part belongs to the widely used BC546 series of NPN transistors, which are industry-standard replacements for older 2N3904 equivalents in many legacy designs. The BC546A specifically denotes a subset with higher or more tightly controlled current gain, differentiating it from lower-gain variants within the same voltage and current rating envelope.
