BC847B,235 datasheet by NXP Semiconductors

BC847B,235 Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for the BC847B,235?
  The maximum operating temperature range for the BC847B,235 is -40°C to 150°C.
• Can I use the BC847B,235 as a switch?
  Yes, the BC847B,235 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)). It's better suited for amplifier applications.
• How do I choose the right resistor values for the base and collector circuits?
  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 datasheet's recommended values and then adjust based on simulation or experimentation.
• What is the maximum current that the BC847B,235 can handle?
  The maximum collector current (IC) for the BC847B,235 is 100 mA, and the maximum emitter current (IE) is 150 mA.
• Can I use the BC847B,235 in a high-frequency application?
  The BC847B,235 has a transition frequency (fT) of 300 MHz, making it suitable for low- to medium-frequency applications. However, it may not be the best choice for high-frequency applications above 100 MHz.
