Transistors - Bipolar (BJT) - Single

BC857B-TP is a commonly used type of single, bipolar junction transistors (BJT) and is ideal for signal and switching applications due to having good gain band width, high transition frequency, and high input impedance. A BJT consists of three terminals (collector, base, and emitter) and its efficient switching capabilities are largely dependent on how electric current travels between those terminals. It is worth noting that the name ‘bipolar’ is derived from the fact that electric current travels in the form of both electrons (negatively charged) and their positive hole counterparts.

Working Principle of BC857B-TP

The working principle of BC857B-TP is relatively simple. An electric current is applied on either side (collector and emitter) of the BJT, creating an external electric field that then causes a majority of the current to be collected at the collector terminal while allowing a far lesser portion of the electric current to pass into the base terminal. This allows for the current to convert from its form of AC to DC, helping to create electric output signals which are typically then applied for purposes like signal amplification or signal switching.

BC857B-TP Application Field

The application fields of BC857B-TP are incredibly vast; it is commonly used in a wide range of products such as amplifiers, voltage regulators, oscillators, power supplies, measurement circuits, transistor radios, and many other electronic devices. Additionally, BC857B-TP is often used in automotive applications as well, most notably as the input stage of on board computers, steering systems, and body control modules. Additionally it can also be used in high frequency and analog applications.

The wide applications of BC857B-TP are due to its capability to respond quickly to changes in voltage, making it especially ideal for switching operations. Additionally, its small size, low cost, and low power requirements make it a great candidate for most applications.

Conclusion

Despite its relatively simplistic nature, the BC857B-TP is an incredibly versatile transistor which is capable of being used in a vast array of applications. Due to its good gain band width, high transition frequency, and high input impedance, it is ideal for signal and switching applications. Additionally its small size and low power requirements make it a great option for many electronic products, from transistor radios to automotive applications.
