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.
