BC850CW,115 Description

Short technical summary and product information.

The BC850CW,115 is an NPN general purpose bipolar junction transistor manufactured by Nexperia. It is designed for low-current, low-voltage applications, with a maximum collector-emitter voltage of 45V and a continuous collector current of 100mA. The transistor offers a high DC current gain (hFE) ranging from 420 to 800 at 2mA collector current, ensuring consistent performance in amplification stages.

 

This transistor features a transition frequency of 100MHz, making it suitable for audio-frequency and general switching applications. It exhibits low noise performance, with a maximum noise figure of 4dB at low frequencies, ideal for use in tape recorders, hi-fi amplifiers, and other audio equipment. The device is also characterized by low collector-base and emitter-base cutoff currents, ensuring minimal leakage.

 

The BC850CW,115 is supplied in a surface-mount SOT-323 (SC-70) package with gull-wing leads, suitable for automated assembly. It is rated for operation up to 150°C junction temperature and has a total power dissipation of 200mW when mounted on an FR4 PCB. The PNP complementary parts are BC859W and BC860W.
