Absolute Maximum Ratings

  • Collector-Emitter Voltage (VCEO): 40V
  • Collector-Base Voltage (VCBO): 60V
  • Emitter-Base Voltage (VEBO): 6V
  • Collector Current (IC): 200mA
  • Base Current (IB): 20mA
  • Power Dissipation (Pd): 625mW

Miscellaneous Information

  • The 2N3904 is a general-purpose NPN bipolar junction transistor (BJT).
  • Its package type is TO-92, which is a popular small signal package used for transistors and other electronic components.
  • The maximum power dissipation of the transistor is 625mW, which means it can handle up to 625mW of power before it begins to overheat.
  • The maximum collector current of the transistor is 200mA, which means that it can handle up to 200mA of current flowing through the collector terminal.
  • The maximum collector-emitter voltage is 40V, which means that the transistor can handle up to 40V between the collector and emitter terminals before it breaks down.
  • The DC current gain of the transistor is typically between 100 and 300, which means that the current flowing through the collector is amplified by a factor of 100 to 300 times the current flowing through the base terminal.
  • The transistor can be used in a wide range of applications, including amplification, switching, and oscillation. Its low cost, small size, and versatility make it a popular choice for hobbyists and professionals alike.

About Admin

Hey friends, Thanks a bunch for stopping by this site! I am an engineer with a Bachelor of Engineering in Electronics and Telecommunication. One of my passions is gathering information from all sorts of electronics books and tutorials. I then take that information and compile it into a language that is super easy to understand. My goal is to make those complex electronics circuit concepts and technical terms much more accessible for all the new and budding electronics engineers out there. I can also design customized circuit diagrams as required by the users.
If you have any questions related to this field, please do not hesitate to drop a comment! I am always here and ready to help you out with any queries you might have. I cannot wait to hear from you!
