![]() When operating as a switching, the transistor will function in the Saturation and Cut-Off Region. But primarily, you can use it either as each of the following: 2n3904 pins-As a switch ![]() The 2N3904 is useful in an extensive range of applications. 2N3904-based electronics projectsįig 3: Power transistors on the black surface Lastly, it functions best at an operating and storage temperature of -55 – 150 degrees celsius.Furthermore, with a 625 milliwatt maximum collector dissipation and 300 MHz maximum Transition Frequency, the transistor has a 5 dB noise level.Thirdly, it has a 40V Collector-Emitter Voltage and a 6V maximum emitter-Base Voltage.Also, it features a DC Current Gain (hFE) of 40 to 300 and a 200mA maximum collector current.First, it is an NPN bipolar junction transistor in a TO-92 package type.Finally, It has a collector pin / Pin 3 via which electric current drains out of the transistor.įig 2: 3D Rendering of TO-92 package on white surface.It’s imperative in biasing control of the transistor. Also, we have Pin 2, which operates as the existing base pin.Pin 1 is the emitter pin via which emitter voltage/ current leaves the transistor.What are 2n3904 pins?ĢN3906 transistors have three pains whose functions are as follows: Join us as we elaborate on 2n3904 pins, electronic applications, and other details of the 2N3906 transistor. It is prevalent in many hobbyist projects for electronic functions like amplification and switching. Used for making siren or dual Led or Lamp flasher.The 2n3904 ranks among the popular transistors that you’ll find in electronic components.Used in inverter and converter circuits.It is used in the various switching applications.Optimal for loads with high peak voltage upto 40V.Used to switch high voltage low current loads.The emitter-base voltage of the transistor is 5V due to which it can also be used at the output of microcontrollers. ![]() On the other hand if you want to use it as a switch then you can drive any load under 200mA with this transistor for example Relays, LEDs, high power transistors etc. Moreover it can be used to amplify any type of small signal. It can also be used as an audio preamplifier or in any other audio related circuit. Where & How to Use 2N3906 Transistor:ĢN3906 can be used in many projects for example it can be used in audio amplifier circuits for general or small amplification requirements. NPN Complementary of 2N3906 is 2N3904 Replacement and Equivalent:īC557, 2N2907, BC556, A1015, C945, 2N4403, 9014, BC527, BC558, BC559 (The pin configuration of the equivalent transistors may different from the 2N3906, therefore it is suggested to always confirm the pin configuration of the transistor you are replacing in the circuit. Continuous Collector current (IC) is 200mA.Max Storage & Operating temperature Should Be: -55 to +150 Centigrade.Minimum & Maximum DC Current Gain (h FE): 100 – 300.Max Transition Frequency (fT): 2 50 MHz.Max Collector Dissipation (Pc): 625 miliWatt.Max Collector-Emitter Voltage (V CE): 40V.Moreover the max collector dissipation value, DC current gain value also makes it ideal to use in wide variety of simple audio frequency applications. The max collector current of the transistor is 200mA therefore it can be used to drive any load which falls under 200mA or 0.2A. The transistor is manufactured to perform general purpose tasks in electronic circuits hence it can be used for any general purpose requirement in electronic circuits that fall in its max specification values. This is also a famous transistor among hobbyists and students because it has been used in wide variety of electronic hobby and educational projects.
