2N2904 - Central Semiconductor

2N2904 Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for the 2N2904?
  The maximum operating temperature range for the 2N2904 is -55°C to 150°C.
• Is the 2N2904 suitable for high-frequency applications?
  The 2N2904 is a general-purpose transistor and is not optimized for high-frequency applications. It has a transition frequency (fT) of around 300 MHz, which may not be sufficient for high-frequency applications.
• Can I use the 2N2904 as a switch?
  Yes, the 2N2904 can be used as a switch, but it's not ideal for high-current switching applications due to its relatively low collector current rating (IC) of 600 mA.
• What is the minimum beta (current gain) of the 2N2904?
  The minimum beta (current gain) of the 2N2904 is around 100, but this can vary depending on the specific batch and operating conditions.
• Is the 2N2904 compatible with automotive applications?
  The 2N2904 is not AEC-Q101 qualified, which means it may not meet the stringent requirements for automotive applications. However, it can still be used in automotive applications if the specific requirements are met, such as operating temperature range and reliability.
