BC547C B1G

Single Bipolar Transistors Overview

The BC547C B1G is an NPN silicon general-purpose transistor manufactured by Taiwan Semiconductor Corporation. It is housed in a TO-92 plastic package with three leads. The device features a maximum collector current of 100 mA and a collector-emitter voltage rating of 45 V. It offers a minimum DC current gain (hFE) of 420, ensuring high amplification capability. The component supports a maximum power dissipation of 625 mW and operates at junction temperatures up to 150 °C.

Single Bipolar Transistors Feature Summary

• NPN silicon construction for general-purpose switching and amplification
• High DC current gain (hFE) of 420 minimum for sensitive signal processing
• TO-92 through-hole plastic package for standard PCB mounting

Single Bipolar Transistors Applications

• General purpose switching circuits
• Small signal amplification stages
• Driver circuits for low-power loads

Single Bipolar Transistors Procurement Notes

Verify the manufacturer marking on the component body matches Taiwan Semiconductor specifications. Confirm the suffix 'B1G' corresponds to the specific tape-and-reel or bulk packaging configuration required for your assembly line. Ensure the datasheet version aligns with the production batch date code to guarantee parameter consistency.

Single Bipolar Transistors Selection Notes

Select this component when a high-gain NPN transistor is required for low-current applications. The BC547C variant provides superior hFE compared to lower grade versions. Consider the TO-92 package constraints for thermal management and board space. Verify that the 45V breakdown voltage meets the circuit's peak operating requirements.

Single Bipolar Transistors Part Context

This part belongs to the BC547 series of NPN general-purpose transistors. It serves as a complement to PNP devices like the BC557. The series is widely used in consumer electronics and industrial control systems due to its reliability and cost-effectiveness. The 'C' designation indicates the highest binning for current gain within the standard family.

Single Bipolar Transistors Replacement Considerations

Compatible substitutes include BC547C from other manufacturers such as ON Semiconductor or NXP, provided pinouts and electrical ratings match. Ensure the replacement maintains the same TO-92 package and hFE binning for equivalent performance.
