2N2913

The 2N2913 transistor is one of the first widely available transistor arrays which has been around since the 1950s. It is also one of the most widely used and versatile transistors in the world. The 2N2913 is a three-terminal NPN transistor array which was developed primarily for single-ended low-level audio applications.

The 2N2913 is used in wide range of applications, including receivers and amplifiers. It is suitable for contending high-level audio signals and is also utilised to reduce the noise levels in audio signals. It is also used in some frequency synthesizers, pulse generators and more. The 2N2913 is also found in certain switching applications, such as switches and timers.

The 2N2913 array consists of three NPN transistors connected in an ‘open collector’ configuration. This configuration allows for the transistors to operate together as a single unit and to share a common emitter. This helps to save space and power, which is useful in portable devices. The open collector arrangement also allows for control signals to be easily received from, and sent to, the transistor array.

The working principle of the 2N2913 is relatively simple. It operates by manipulating the current flow between the base and collector of the three NPN transistors within the array. The current which flows from the base to the collector is controlled via the voltage applied to it. Depending on the voltage applied to the base, the current can flow at different levels, which is how the 2N2913 produces its wide range of audio and control signals.

The unique design and construction of the 2N2913 makes it a reliable and efficient transistor array. The multiple transistors in the array share a common emitter, which helps to reduce the amount of current needed to power the array. Furthermore, the open collector arrangement allows for easy control and versatility, further adding to its list of advantages.

In conclusion, the 2N2913 transistor array is an incredibly versatile component which has been used in a wide range of applications since the 1950s. It has a simple working principle and is easy to control and use, making it a popular choice for those seeking to reduce their component count and save on space and power.
