BC857CW-QX Description

Short technical summary and product information.

BC857CW-QX is a PNP general-purpose transistor from Nexperia, designed for low-current switching and amplification applications. It features a maximum collector-emitter voltage of -45V and a collector current rating of 100mA, with a peak collector current of 200mA. The device offers a DC current gain (hFE) of at least 420 at 2mA and 5V, and a transition frequency of 100MHz, making it suitable for high-frequency signal processing.

 

The transistor is qualified according to AEC-Q101, making it suitable for automotive applications. It operates at junction temperatures up to 150°C and can be stored in a range of -65°C to 150°C. Power dissipation is rated at 200mW. The BC857CW-QX is available in a compact SOT323 (SC-70) surface-mount package, which is ideal for space-constrained PCB designs.

 

Typical applications include general-purpose switching, signal amplification, and driving small loads in automotive and industrial electronics. The device is a complement to the NPN BC847CW-Q transistor, allowing convenient push-pull circuit designs.
