Description
TO-92 Plastic-Encapsulate Transistors 2N3904 Product Introduction:
Maximum withstand voltage
Firstly, there is the maximum withstand voltage. The maximum withstand voltage of this transistor is 40V, which means that the circuit needs to maintain a working voltage below 40V during use, otherwise it may cause device damage or burnout and other faults. Therefore, special attention should be paid to this parameter when designing the circuit to ensure its normal operation.
Maximum current
Next is the maximum current. The maximum current of this transistor is 200mA, which means that during operation, its passing current should be less than or equal to 200mA. If the current flowing through the device in the circuit is too large, it will cause it to overload and fail. Therefore, in the process of circuit design, it is necessary to select appropriate devices according to actual needs to meet current requirements.
Corona withstand pressure
Corona withstand voltage refers to the voltage that electrical equipment can withstand under the condition of electric shock discharge, which is another term for electrical strength. The corona withstand voltage is 300V, which means that when there is a sudden voltage change or transient voltage in the circuit, the device can withstand a voltage surge of 300V without being damaged. The improvement of this performance parameter can significantly enhance the anti-interference ability of transistors in circuits.
Amplification factor (minimum)
The amplification factor is an important performance parameter of a transistor and also one of the indicators to measure its amplification capacity. The minimum amplification factor is 100, which means that when using this transistor for amplification, its amplification factor cannot be lower than 100. This feature enables 2N3904 to be widely used in circuits such as electronic amplifiers, signal generators, audio amplification, and power control.
Voltage amplification factor (minimum)
The voltage amplification factor is also an important performance parameter of a transistor, which can reflect the voltage ratio between its output signal and input signal. The minimum voltage amplification factor is 60V/V, which means that its output voltage should be more than 60 times the input voltage. This parameter is closely related to the amplification factor and can help designers determine the amplification factor of transistors in the circuit.
Packaging type
Finally, there is the encapsulation type. This transistor adopts TO-92 plastic packaging, with a compact appearance, beautiful and reliable. This packaging method can effectively prevent the device from being subjected to external shocks, improve its seismic performance, and thus extend its service life.
