2N4401BU Frequently Asked Questions (FAQs)

  • The maximum operating temperature range for the 2N4401BU is -55°C to 150°C.
  • Yes, the 2N4401BU can be used as a switch in high-frequency applications up to 100 MHz, but it's essential to consider the transistor's transition frequency (fT) and ensure proper impedance matching to minimize losses.
  • To ensure proper biasing for linear amplifier applications, set the base voltage (VBE) between 0.6V to 0.8V, and the collector-emitter voltage (VCE) between 2V to 10V, depending on the specific application requirements.
  • The recommended storage temperature range for the 2N4401BU is -55°C to 150°C, with a relative humidity of 60% or less.
  • The 2N4401BU has a maximum collector-emitter voltage (VCEO) of 40V, so it's suitable for low- to medium-voltage applications. For high-voltage applications, consider using a transistor with a higher voltage rating.
