BC547CG

Single Bipolar Transistors Overview

The BC547CG is an NPN silicon epitaxial planar transistor from the onsemi BC546-BC548 series, housed in a TO-92 (Case 29) 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 range of 420 to 800 at Ic=2.0 mA and Vce=5.0 V. Key electrical characteristics include a transition frequency of 300 MHz and a maximum power dissipation of 625 mW at 25°C ambient temperature.

Single Bipolar Transistors Feature Summary

• NPN epitaxial silicon planar design for general-purpose amplification
• High DC current gain suitable for sensitive signal processing
• Lead-free packaging compliant with environmental directives

Single Bipolar Transistors Applications

• General-purpose amplifier circuits
• Switching applications requiring moderate voltage ratings
• Audio pre-amplifier stages

Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix 'G' indicates lead-free compliance as per onsemi documentation. Confirm the package style matches the required pinout configuration for your PCB layout. Ensure the bulk shipping quantity aligns with production requirements. Check for any regional distribution restrictions or RoHS declarations prior to finalizing procurement orders.

Single Bipolar Transistors Selection Notes

Select this component when high current gain is required for low-level signal amplification. The 45V rating suits standard low-voltage logic and analog interfaces. Compare against BC547A or BC547B if lower gain thresholds are acceptable for cost optimization. Verify thermal management needs given the 625mW dissipation limit in free air.

Single Bipolar Transistors Part Context

Part of the BC546/BC547/BC548 family offering complementary PNP devices (BC556/557/558). The 'C' suffix denotes the highest gain bin within the BC547 lineup. Designed for through-hole mounting in standard TO-92 configurations. Widely used in consumer electronics and industrial control boards.

Single Bipolar Transistors Replacement Considerations

Direct substitutes include BC547C from other manufacturers. Verify pinout compatibility (Collector-Base-Emitter vs Base-Collector-Emitter) before substitution. Check gain bin specifications to ensure equivalent performance in high-gain applications.
