2PA1774SMB,315

Transistors - Bipolar (BJT) - Single

The 2PA1774SMB,315 is a Silicon NPN transistor manufactured by Panasonic. This type of transistor is a bipolar junction transistor or BJT, which is designed with a single p-n junction. This allows for the NPN transistor to connect two n-type semiconductor materials within the crystal structure, one of which is the base region with a larger bandgap. This provides a high voltage, low current transistor.

Application Field

The 2PA1774SMB,315 is suitable for high-speed switching applications due to its wide ranging voltage supply, low capacitive switching and high collector current. It is also suitable for amplifier and small signal applications, due to its wide frequency response and high gain.

Working Principle

The 2PA1774SMB,315 operates on a principle known as the collector current law. This law states that the base current that flows into the base region of the transistor affects the current flowing into the collector. This results in a current amplification factor that increases the power across a load placed between the collector and the emitter.

By applying a voltage to the base of the transistor, it will allow an increased current to flow from the collector to the emitter. This increases the resistance across the load, resulting in a higher voltage gain. This application is used for many amplifier and small signal applications.

It is also possible for the 2PA1774SMB,315 to act as a switch by controlling the current that flows through the collector. This is done by using an external load to control the resistance of the collector-emitter junction.

The 2PA1774SMB,315 is also capable of withstanding high temperatures and has a low power dissipation. This makes it ideal for use in high temperature applications such as those in the automotive and avionics industries.

Conclusion

The 2PA1774SMB,315 is a Silicon NPN transistor capable of a wide range of switching duties, making it suitable for many applications. It is mainly used for high-speed switching, amplifier and small signal applications. The transistor works on the principle of the collector current law in order to amplify current or to act as a switch. This transistor is also capable of withstanding high temperatures and has a low power dissipation for use in automotive and avionic applications.
