BC547BRL1G Description

Short technical summary and product information.

The BC547BRL1G is a silicon NPN bipolar junction transistor designed for general-purpose amplifier and switching applications. Key electrical ratings include a maximum collector-emitter voltage (VCEO) of 45V, a continuous collector current of 100mA, and a power dissipation of 625mW at 25°C ambient temperature. The transistor offers a DC current gain (hFE) range of 200 to 450 at 2mA collector current, making it suitable for low-to-medium gain amplification stages. The transition frequency (fT) is typically 300MHz, enabling use in moderate-frequency circuits.

 

This device is housed in a TO-92 (TO-226) through-hole package with formed leads, allowing easy insertion into standard PCB layouts. The operating junction temperature range spans -55°C to +150°C, with a junction-to-ambient thermal resistance of 200°C/W. The BC547BRL1G is part of the BC547 series, available in multiple gain classifications (A, B, C) for design flexibility.
