The BCV47-QVL is a Darlington Transistor manufactured by Nexperia. It has three pins arranged in SOT23/TO-236AB format. It is typically used to amplify, switch, or modulate signals in a range of electronic applications. It is designed to have rated collector current up to 700mA and a maximum collector emitter voltage of 40 V. It also has a low base-emitter saturation voltage, a low level of noise, and a low internal resistance. This device is typically used for switching/amplifying signals in a variety of consumer electronics, such as cameras, telephones, computers, and smaller DC motors.
