FMMT491TC is a darlington-connected, NPN complementary silicon-based fan out transistor array, with a built-in driver transistor. This type of device is found in a wide range of industries, such as audio and video, motor control, industrial automation, and consumer applications.
The array consists of two NPN transistors, each with a built-in collector resistance of the driver transistor, which ensures the output signal is properly amplified and remains stable under varying load conditions. The FMMT491TC features an improved high-frequency response for improved signal transfer characteristics and signal-to-noise ratio.
FMMT491TC features a high voltage capability, making it suitable for applications that are exposed to a large voltage variation. Additionally, FMMT491TC transistors are protected from excessive currents by the built-in collector resistance, and the high-current gains offered by the device make it suitable for numerous applications.
The working principle of the FMMT491TC is quite simple. It is basically an array consisting of two transistors that are connected in a \'Darlington\' configuration. This means that one transistor acts as a driver and the other as the output device. The driver transistor is used to amplify the input signal voltage and current, while the output transistor is used to provide the amplified voltage and current to the load.
The advantage of this \'Darlington\' configuration is that it can produce a high current gain, which is essential for powering high-performance applications. However, the output of this configuration is also non-linear and can lead to distortion in the signal if used in applications that demand high quality sound. To avoid this problem, it is recommended to use a separate driver transistor for the output stage of the amplifier.
FMMT491TC is a versatile device with many applications. In audio and video systems, it is used to provide a high-current capability for powering loudspeakers, subwoofers, amplifiers, and other high-powered audio components. In consumer applications, it is used in motor control, industrial automation, and other applications that involve high current gains.
FMMT491TC is also ideal for use in RF communication systems, as its performance is not affected by any variation in the frequency of the signal. In these applications, it can provide a stable high-voltage/low-current signal and can improve signal-to-noise ratio.
In summary, the FMMT491TC is a versatile device that can be used in a variety of applications, such as audio and video systems, motor control, industrial automation, and consumer applications. Its built-in driver transistor ensures the output signal is properly amplified and remains stable under varying load conditions, and its high-current gains make it suitable for many applications.
