BC847QASX Application Field and Working Principle

The BC847QASX is a general-purpose NPN transistor array composed of three discrete NPN transistors, which can be used as pre-drivers and in series-circuit configurations. It is commonly utilized in consumer, automotive and industrial applications.

Application Field

The BC847QASX is used in a variety of consumer, automotive and industrial applications. In consumer applications, it is commonly used as a pre-driver in data sheet readers and motion control systems. In automotive applications, it is used as a switching element in motor drivers, powertrains and brakes. In industrial applications, it is used for switching and driving large loads, and for controlling drivers and actuators.

Working Principle

The BC847QASX is composed of three discrete NPN transistors, arranged in common-emitter configuration. This configuration gives the transistor array a very high gain, allowing it to be used for high-efficiency, high-voltage switching applications. When driven, the transistors will switch between the “on” and “off” states, allowing current to flow through the array, thus actuating whatever circuitry is connected to it.

When one of the transistors is turned on, it will cause the current to flow, thus producing a voltage. This voltage will in turn cause the other two transistors to turn on, thus producing a larger voltage in the secondary direction. This larger voltage will in turn cause the transistors to turn off, allowing current to flow in the opposite direction, thus allowing the given workload to be done effectively.

Conclusion

The BC847QASX transistor array is a powerful and versatile tool for use in a variety of consumer, automotive, and industrial applications. Its three NPN transistors are configured in a common-emitter configuration, giving it an extremely high gain, allowing it to be used for efficient, high-voltage switching. Its ability to switch between the “on” and “off” states makes it an ideal choice for controlling drivers and actuators, and it is commonly utilized in data sheet readers and motion control systems.
