2N3904BU Frequently Asked Questions (FAQs)

  • The maximum operating temperature range for the 2N3904BU is -55°C to 150°C.
  • Yes, the 2N3904BU can be used as a switch, but it's not recommended for high-frequency switching applications due to its relatively low transition frequency (ft) of 250 MHz.
  • To ensure proper biasing, set the base voltage (VBE) to around 0.7V and the collector-emitter voltage (VCE) to around 1V to 5V, depending on the specific application requirements.
  • The maximum collector current (IC) rating for the 2N3904BU is 200 mA.
  • No, the 2N3904BU is not suitable for high-voltage applications, as its maximum collector-emitter voltage (VCE) rating is 40V.
