BC857B Description

Short technical summary and product information.

The BC857B from Philips is a single bipolar junction transistor (BJT) belonging to the Transistors - Bipolar (BJT) - Single, Pre-Biased category. This component is designed for general-purpose applications and offers a maximum DC collector current of 0.2 A and a collector-emitter voltage (VCEO max) of 45V.

 

Key electrical characteristics include a collector-base voltage (VCBO) of 50V, an emitter-base voltage (VEBO) of 5V, and a gain bandwidth product (fT) of 100 MHz. The maximum power dissipation is rated at 250 mW. The transistor exhibits a maximum DC current gain (Hfe) of 220 at 2 mA and 5V, with a minimum DC collector-base gain (Hfe) of 220 under the same conditions.

 

This device operates within a temperature range of -65°C to 150°C. It is supplied in a surface-mount SOT-23 package, typically on a reel with a standard pack quantity of 3000 units, making it suitable for automated assembly processes.

 

The BC857B is a reliable choice for engineers seeking a general-purpose PNP transistor with established specifications for various electronic circuits.
