.The BC856A-QR is a group of general-purpose, PNP bipolar transistors. This family of transistors is manufactured by Nexperia and includes three subtypes: BC856-Q, BC857-Q, and BC858-Q. All of these transistors have a maximum DC collector current of 100 mA and a maximum voltage rating of 65 V. The BC856A-QR transistors can be used in a variety of applications, including analog amplification, voltage regulation, audio frequency amplifier stages, switching circuits, and more. Thanks to their high gain, low noise, and low power output, they are ideal for projects requiring low power, low power consumption, and high levels of accuracy.
