BC547BTAR

Single Bipolar Transistors Overview

The BC547BTAR is an NPN silicon epitaxial planar transistor manufactured by onsemi. It features a maximum collector current of 100 mA and a collector-emitter voltage rating of 45 V. The device operates within a junction temperature range of -55 °C to +150 °C and has a maximum power dissipation of 625 mW. It utilizes a TO-92 package with three terminals. The minimum DC current gain (hFE) for the 'B' grade is specified at 200.

Single Bipolar Transistors Feature Summary

• NPN epitaxial silicon planar design
• High voltage capability up to 45 V
• Low noise performance characteristics
• Lead-free packaging compliant with RoHS directives

Single Bipolar Transistors Applications

• General purpose amplifier circuits
• Switching applications
• Audio pre-amplifier stages

Single Bipolar Transistors Procurement Notes

Verify the manufacturer marking matches onsemi specifications. Confirm the package type is TO-92 and the pinout corresponds to Collector, Base, Emitter. Ensure the part number suffix indicates the correct tape and reel configuration if required for automated assembly processes.

Single Bipolar Transistors Selection Notes

Select this component when a general-purpose NPN transistor with 45 V breakdown voltage is required. The 'B' grading ensures a minimum hFE of 200, suitable for moderate gain applications. Consider complementary PNP devices from the BC557 series for matched pairs in push-pull configurations.

Single Bipolar Transistors Part Context

This component belongs to the BC546/547/548 family of NPN transistors. The BC547 variant specifically offers a 45 V collector-emitter voltage rating, distinguishing it from the BC546 (65 V) and BC548 (30 V). It is designed for low-power switching and amplification tasks in consumer and industrial electronics.

Single Bipolar Transistors Replacement Considerations

Compatible substitutes include BC547B, BC547CTAR, and BC547BTA. Verify that replacement parts maintain the same 45 V VCEO rating and TO-92 package dimensions to ensure mechanical compatibility.
