![]() ![]() To get good and long term performance from this transistor it is suggested to not drive loads more than 100mA, always use a suitable base resistor, do not provide collector-emitter voltage more than 40V and always operate or store in temperatures above -55 centigrade and below +150 centigrade. When using as an amplifier it can be used in audio amplification stages, as an amplifier to drive small speakers, as an audio preamplifier and it can also be used in amplification stages of RF applications. The maximum collector current of the transistor is 200mA therefore user can drive loads under 200mA in their electronic applications, Moreover 2N3904 also work good as an amplifier, the total device dissipation is 625 milliwatt due to which it can also be used for audio and RF signal amplification purposes.ĢN3904 can be used in any electronic applications which fall under its electrical characteristics, let suppose if you want to switch a load in an electronic application that requires current under 200mA then this transistor will work quite well and you can drive variety of loads with this transistor for example relays, high power transistors, LEDs, a portion of an electronic circuit etc. 2N3904: 323Kb / 2P: NPN SILICON TRANSISTOR Daya Electric Group Co. It can be used in wide variety of electronic applications for switching and amplification purposes. 2N3904: 52Kb / 3P: NPN Silicon Transistor (General small signal application) Central Semiconductor C. It is mostly used by electronic students and hobbyists in their projects, but it is also used in commercial electronic products. Max Storage & Operating temperature Should Be: -55 to +150 CentigradeĢN2222, S8050, 2N4401, BC537, SS9013 (Pin configuration of some transistors may different from 2N3904 therefore check pin configuration before replacing in a circuit)ĢN3904 Transistor Explained / Description:ĢN3904 is a widely used general purpose transistor.Minimum & Maximum DC Current Gain (h FE): 40 – 300.2N3904 has a gain value of 300 this value determines the amplification capacity of the transistor. Max Collector Dissipation (Pc): 625 miliWatt 2N3904 is a NPN transistor hence the collector and emitter will be left open (Reverse biased) when the base pin is held at ground and will be closed (Forward biased) when a signal is provided to base pin.This 2N3904 NPN transistor is very popular, so it can be used like an amplifier and simple. This type of NPN transistor is mainly designed for medium voltage, low power applications and it operates at moderately high speeds. Max Collector-Emitter Voltage (V CE): 40V The 2N3904 is a common NPN BJT used in the applications of general-purpose switching or low-power amplifying applications.*This information is for general informational purposes only, we will not be liable for any loss or damage caused by the above information.Advertisements Features / technical specifications: NPN Transistor (2N3904) Polarity: NPN Collector- Emitter Voltage (VCEO) Max: 40 V Emitter-Base Voltage (VEBO): 6 V DC Currency Max: 0.2 A DC Collector /.

The company's products are designed to be energy efficient, reliable, and cost-effective, and are used in a variety of applications, including portable electronics, industrial automation systems, renewable energy systems, and automotive electronics. However, STMicroelectronics assumes no responsib ility for the consequences of use of such information nor for any infringement of patents or other rights of third parties which may result from its use. The total device dissipation of the 2N3904 is 625mW, while the BC547 is 500mW. Your circuit is only powered with 9V, and the current passing through each transistor is limited to less than 20mA, so any replacement that can handle eg. The maximum collector current of the 2N3904 is 200mA, while the collector current of the BC547 is 100mA. The 2N3904 is rated for a maximum of 40V between Collector and Emitter, and 200mA Collector current. ON Semiconductor offers a broad portfolio of power management, analog, and discrete semiconductors, including power MOSFETs, diodes, rectifiers, and voltage regulators, among others. Information furnished is believed to be accurate and reliable. When changing a transistor, the Collector to Emitter voltage is vital to look at, although a difference of 10V isnt a concern unless your load is under 40V. ![]() The company was founded in 1999 and is headquartered in Phoenix, Arizona. ON Semiconductor is a publicly traded company that designs, develops, and manufactures a wide range of semiconductor products for various applications, including automotive, computing, consumer, industrial, and communications markets.
