The 2N3904 is a very popular and frequently used transistor, classified as a bipolar (BJT) single. It has a wide range of application fields, and its working principle is quite simple. This article provides an overview of the 2N3904_D81Z, its common application fields, and its basic operational principle.

2N3904_D81Z Characteristics and Specifications

The 2N3904_D81Z is a commonly used small signal transistor. It consists of 3 components: an emitter, a collector and a base. The collector and emitter are both connected to terminals, which allow current to flow through. The 2N3904_D81Z is considered a NPN-type transistor, as the base voltage is higher than the collector voltage. This type of transistor is often used in electronic circuits as a switch or amplifier.

This device is able to operate in a wide range of temperature and can withstand a maximum collector-emitter voltage of 40V. It has a current gain of 100, which is considered very high for its size. This means that it can easily handle the current drawn by typical electronics.

The 2N3904_D81Z also has low collector-emitter saturation voltage and can provide excellent linearity. This means that current and voltage can both pass through the device without suffering from significant changes. It can also deliver an output current of up to 500 mA, which is more than enough for most applications.

Common Application Fields

The 2N3904_D81Z has a variety of applications. It is commonly used to control higher current loads in circuits. It can be used as a switch for activating or deactivating circuits. It is also used as an amplifier for increasing the strength of signals. This device is commonly used in electronic devices, such as LED lighting, computers, and other consumer electronics.

This device is also used in communications circuits. It is used to convert a low power input signal into a stronger and more reliable output signal. This is especially useful in wireless devices, such as cell phones, which need to transmit and receive signals with high clarity.

Working Principle

The basic working principle of the 2N3904_D81Z is quite simple. The base voltage is used to control the flow of current between the collector and emitter terminals. When the base voltage is increased, more current can pass through the device. Conversely, when the base voltage is decreased, the flow of current is reduced.

When the 2N3904_D81Z is used as an amplifier, the base voltage is increased to allow more current to pass through. This increases the strength of the output signal, making it louder and clearer. When the 2N3904_D81Z is used as a switch, the base voltage is reduced to reduce or stop the current flow.

Conclusion

The 2N3904_D81Z is a commonly used and highly versatile transistor. It is classified as a bipolar (BJT) single, and can be used in a variety of application fields. Its working principle is relatively simple, and it can deliver excellent performance in many scenarios. This device is particularly popular in consumer electronics, communications, and LED lighting circuits.
