FZT2907ATA

The FZT2907ATA is an NPN silicon Giran Junction Transistor package by Fairchild Semiconductor. It is usedin small signal applications, specifically those which require up to 0.2 watts of power dissipation. This is mostly used in amplifier and switching applications, especially those which require low noise levels and moderate gain.The FZT2907ATA is a medium-power device, capable of operating at up to 70V and with current gains ranging from 30 to 300. This range and moderate power output makes the FZT2907ATA suitable for use in a variety of applications including amplifiers, switching circuits, and oscillators.

The FZT2907ATA is an epoxy-molded plastic package which comes in the TO-18 format. This is a single turn-on transistor with a 2-pin configuration, one for the base and one for the collector. Compared to other similar devices, the FZT2907ATA features higher gain, better noise performance, and a lower power loss rating.It has a maximum power dissipation of 0.2 watts (at 25℃).

Working Principle

The FZT2907ATA works on the principle of bipolar junction transistors (BJT). A BJT is a three-terminal electronic device composed of three layers of semiconductor material. In a BJT, electrons are attracted to the positively-charged layer of semiconductor material on one side, and repulsed by the negatively-charged layer on the other side. The middle layer, known as the base layer, provides an area in which the electrons can transition between the two layers, creating a current flow. A BJT works by allowing a small amount of current to flow from the base layer to the collector layer, where it can be amplified, or from the base layer to the emitter layer, where it can be turned off. This ability to control the current flow makes BJTs suitable for a variety of applications, such as amplifiers, switches, and oscillators.

Application Fields

The main application field for the FZT2907ATA is amplifier circuits. The device has a good noise performance and range of gains (30 to 300) that make it well suited for amplifier applications. It is also suitable for use in switching and oscillator circuits.

The FZT2907ATA can be used as an audio amplifier, which is an amplifier designed to amplify a single audio signal. This type of amplifier is typically used to increase the signal level of a stereo or home theater system. The FZT2907ATA can also be used as an amplifier in a power supply circuit, which is often used in electronic circuits to reduce ripple from the DC power source or to boost the output current of the power supply.

The FZT2907ATA is also suitable for use in oscillator circuits. Oscillators are circuits that generate a continuous, periodic signal, often used in radio-frequency (RF) and audio applications. The FZT2907ATA can be used to vary the frequency or amplitude of the signal, or to engage and disengage the signal. The device can also be used in switching applications, such as for signal routing or power control.
