BC549C Frequently Asked Questions (FAQs)

  • The maximum operating temperature range for the BC549C is -55°C to 150°C.
  • Yes, the BC549C can be used as a switch, but it's not recommended due to its relatively low current gain (hFE) and high saturation voltage (VCE(sat)). A dedicated switch transistor like the 2N3904 or 2N4401 would be a better choice.
  • The choice of resistor values depends on the specific application and the desired current and voltage levels. A good starting point is to use the transistor's datasheet values and then adjust based on the specific circuit requirements.
  • The maximum collector current (IC) that the BC549C can handle is 100 mA.
  • The BC549C is not suitable for high-frequency applications due to its relatively low transition frequency (fT) of 300 MHz. A transistor with a higher fT, such as the 2N3904, would be a better choice.
