The CXTA14 TR is a single bipolar junction transistor (BJT) designed for applications in transistor-based electronic systems, such as radios and other audio products. It is an isotropic multi-layer metal device, with three semi-conductor layers: a P-type layer, an N-type layers and another P-type layer. These layers are referred to as the collector, the base and the emitter, respectively. When a voltage is applied to the base, it attracts more electrons to the emitter, causing the emitter to become more conductive than the base and the collector. This results in an electric current flowing through the collector and emitter, thus enabling the device to amplify current.

The CXTA14 TR has a maximum voltage of 50 volts, a maximum current of 200mA and a power dissipation of 125mW. Its operating temperature range is -40 to +75 °C and it has a maximum DC current gain of 200.

The device is best suited for use in low-power, low-noise applications, such as low-power audio systems and switch-mode power supplies. The CXTA14 TR is also ideal for use in frequency-controlled systems and oscillators due to its high frequency capability and superior frequency response. Additionally, it is capable of producing high gain at low power levels, making it ideal for use in both RF and low-frequency applications.

The CXTA14 TR works by using the principle of minority-carrier injection, which is also known as the common-emitter current gain. In a device such as the CXTA14 TR, the base is biased with a negative voltage, and electrons are injected from the emitter into the base crystal. These electrons reach the collector and cause a current to flow. As the voltage at the base increases, more electrons are injected, and the current increased accordingly. This results in an electrical current gain at the collector, making the device an ideal choice for amplifying small signals.

In order to determine the gain of the CXTA14 TR, the DC current gain (also known as beta or hfe) must be determined first. The DC current gain is calculated by dividing the collector current (IC) to the base current (IB). The higher the DC current gain, the better the device’s ability to amplify signals.

In addition to its current gain capabilities, the CXTA14 TR also has excellent voltage feedback capabilities. When the voltage at the base increases, the emitter-collector voltage increases accordingly, allowing the device to provide excellent voltage regulation. Additionally, the device can provide stable voltage regulation in a wide range of operating conditions due to its wide range of operating voltages and currents.

Overall, the CXTA14 TR is an ideal choice for low-power, low-noise audio and RF applications. Its high frequency response, voltage feedback and DC current gain capabilities make it well-suited for use in both high-frequency and low-frequency applications. Additionally, its operating temperature range and power dissipation capabilities make it ideal for use in transistor-based electronics.
