BC547BG

Single Bipolar Transistors Overview

The BC547BG is an NPN epitaxial silicon transistor manufactured by onsemi in a TO-92 package. It features a collector-emitter voltage of 45 Vdc and a continuous collector current of 100 mAdc. The device offers a DC current gain (hFE) ranging from 110 to 800 at IC = 2.0 mA, and up to 450 at IC = 10 mA. Key electrical characteristics include a collector-base breakdown voltage of 50 Vdc, emitter-base breakdown voltage of 6.0 Vdc, and a current-gain-bandwidth product of 300 MHz. Total device dissipation is rated at 625 mW at 25°C ambient temperature.

Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix 'G' indicates lead-free status as per onsemi documentation. Confirm the package style matches the required pinout configuration for your PCB layout. Ensure thermal management aligns with the specified junction-to-ambient resistance limits during operation.

Single Bipolar Transistors Selection Notes

Select this component when a standard NPN small-signal transistor with moderate voltage ratings is required. The BC547B variant provides a balanced gain range suitable for most linear and switching applications. Consider the BC547C or BC547A variants if higher or lower minimum gain thresholds are necessary for specific circuit designs.

Single Bipolar Transistors Part Context

This part belongs to the BC546/BC547/BC548 series of NPN general-purpose transistors. It serves as a complement to the BC557 PNP transistor. The series is widely used in consumer electronics and industrial control systems due to its reliability and standardized TO-92 form factor.

Single Bipolar Transistors Replacement Considerations

Compatible substitutes include BC547B, BC547C, and BC547A from onsemi or other manufacturers. Cross-reference datasheets for hFE binning differences and ensure pinout compatibility before substitution.
