BC847B Description

Short technical summary and product information.

The BC847B is a silicon epitaxial planar NPN transistor from STMicroelectronics designed for general-purpose switching and amplification in surface mount applications. It is housed in a miniature SOT-23 plastic package suitable for automated assembly.

 

Key electrical specifications include a maximum collector-emitter voltage (VCEO) of 45V, a maximum collector current (IC) of 100mA, and a peak collector current (ICM) of 200mA. The device offers a DC current gain (hFE) range of 200 to 450 at Vce=5V and Ic=2mA, with a typical transition frequency (fT) of 100MHz. Collector-emitter saturation voltage is typically 0.09V at Ic=10mA.

 

The transistor is well suited for portable equipment and small load switch applications due to its high gain and low saturation voltage. It is supplied in tape and reel packaging for high-volume manufacturing. The complementary PNP type is the BC857B.
