BC856S/ZLH transistors are an integrated circuit that can be used in many applications. They are a combination of multiple BJT (bipolar junction transistors) which are connected together, often in a specific configuration. By using BJT arrays like this, circuit designers are able to simplify a circuit at the same time as providing more functionality than with just one transistor.

The traditional BJT transistor itself is three sided, having a base, emitter, and collector which always has an even current flow of electrons. It can be used for switching, amplification, or even power control. By adding multiple transistors in an array, its functionality increases exponentially, allowing for current sharing and other advantages.

The BC856S/ZLH uses two BJT’s in a single package. This two-transistor array is commonly referred to as a Darlington Pair. This configuration of two transistors provides a higher amplification factor of the current than a standard BJT. This means that the same current can be used to control more power or provide a higher level of gain. In addition, the Darlington Pair offers improved temperature stability, which is beneficial because temperature fluctuations can cause changes in the gain of a transistor.

One application of the BC856S/ZLH is in power supply design. When designing a power supply, it is important to have easy control over the voltage and current. The Darlington Pair allows a high gain, meaning a small change in the base current can result in large fluctuations in the output current. This is useful for regulating the output of the power supply, as small fluctuations in output voltage can be handled with a very low base current.

Another common application for BJT arrays is for driving large loads. By utilizing a Darlington Pair, a small amount of current can be used to switch large amounts of power. This works due to the high current gain of the Darlington Pair, allowing the circuit to provide a large amount of current while drawing a relatively small amount from the base.

With the increasing complexity of electronic devices, the need for high performance transistors like the BC856S/ZLH is ever-increasing. BJT arrays allow for better control of current, increased efficiency, and high levels of current gain. As devices become more powerful and the need for accurate control and efficiency increases, BJT Arrays such as the BC856S/ZLH will become an even more useful tool.
