BC857BLT1G Description

Short technical summary and product information.

The BC857BLT1G is a PNP general purpose bipolar junction transistor manufactured by onsemi (formerly ON Semiconductor). It is designed for general purpose switching and amplification applications. The transistor features a maximum collector-emitter voltage (VCEO) of -45V and a continuous collector current rating of -100mA. It offers a DC current gain (hFE) of 220 minimum at Ic=2mA and Vce=5V, with a transition frequency (ft) of 100MHz, making it suitable for low to medium frequency circuits.

 

The device is housed in the industry-standard SOT-23-3 surface mount package (also known as TO-236-3 or SC-59). The maximum power dissipation is 225mW on an FR-5 board and 300mW on an alumina substrate. It operates over a junction temperature range of -55°C to +150°C. The BC857BLT1G is Pb-Free, Halogen Free/BFR Free, and RoHS compliant. It is AEC-Q101 qualified and PPAP capable for automotive applications.
