BD787G Datasheet/PDFThe BD787G is a single bipolar (BJT) NPN silicon transistor, typically used for switching and amplifier applications. As transistors go, the BD787G is a fairly typical small signal device and can be used in a wide range of projects. It features a high current gain and can output as much as 8 A when used correctly.
The device just is labeled and internally configured as an NPN transistor. It is connected to a base electrode, which forms the means of allowing current flow between emitter and collector. The base requires an appropriate voltage to control the current flow between emitter and collector. In this way, the NPN transistor can be used for both switching and amplifying operations.
The BD787G has a variety of uses, the most common being amplifier configurations. They are commonly used as the final amplifier stages of Class A or Class AB mono or stereo amplifiers. They can be used in preamplifiers, line drivers, and even power amplifiers. For switching purposes, the BD787G is generally used for low-power switching applications such as low voltage/low current control circuits.
The BD787G is also suitable for RF applications such as RF amplifiers and oscillators. This is due to its ability to handle high frequency signals, providing amplification of high frequency signals up to 800 MHz with good linearity. Additionally, the device is also capable of withstanding high voltages up to 80 V, making it suitable for a range of signal switching and amplification applications.
The BD787G has three major sections: the emitter, base, and collector. The emitter supplies a signal input, while the base serves to regulate the flow of current between the collector and emitter. The collector, on the other hand, receives the amplified signal from the base and allows it to be passed out of the device. The components are laid out in an open-base configuration, allowing for easier diagnosis of any problems.
In addition to its use as an amplifier or switch, the BD787G can also be used for RF applications. This can be done by connecting a radio frequency signal to the base and then connecting the collector to the antenna. The antenna will then receive the signal from the transistor and amplify it, providing a sufficient output for the desired application. This is an effective way to apply the transistor to radio frequency applications.
The BD787G is a versatile transistor, offering a wide range of applications including those involving both analog and digital signal amplification and switching. It is a cost-effective device with a high current gain and can be used in a variety of projects. Whether used for RF applications or other more standard amplification and control operations, the BD787G provides an efficient and cost-effective solution.
