2N4861 Frequently Asked Questions (FAQs)

  • The recommended operating temperature range for the 2N4861 is -55°C to 150°C, although the device can withstand storage temperatures up to 200°C.
  • To ensure proper biasing, the 2N4861 requires a Vgs of 0V to -5V, and a Vds of 10V to 30V. Additionally, the device should be operated within the recommended current limits to prevent overheating and ensure reliability.
  • The maximum allowable power dissipation for the 2N4861 is 1.5W, and it is essential to ensure that the device is properly heat-sinked to prevent overheating and thermal runaway.
  • Yes, the 2N4861 can be used in switching applications due to its fast switching times (tr and tf) of 10ns and 20ns, respectively. However, it is essential to ensure that the device is properly driven and biased to prevent overheating and ensure reliable operation.
  • No, the 2N4861 is not a radiation-hardened device. It is not designed to operate in high-radiation environments, and its performance may be affected by radiation exposure.
