2N4858 Frequently Asked Questions (FAQs)

  • The recommended operating temperature range for the 2N4858 is -55°C to 150°C, although it can withstand storage temperatures up to 200°C.
  • To ensure proper biasing, the 2N4858 requires a Vgs of 0V to -5V, and a Vds of 10V to 30V. Additionally, the gate-source voltage should be limited to -5V to prevent damage.
  • The maximum allowable power dissipation for the 2N4858 is 1.5W, and it's essential to ensure the device is properly heat-sinked to prevent overheating.
  • Yes, the 2N4858 can be used in switching applications due to its fast switching times (tr and tf) of 10ns and 20ns, respectively. However, it's essential to ensure the device is properly driven and biased to prevent overheating and reduce electromagnetic interference (EMI).
  • The 2N4858 has a relatively high cutoff frequency (fT) of 1.5GHz, making it suitable for high-frequency applications up to several hundred MHz. However, it's essential to consider the device's parasitic capacitances and inductances when designing high-frequency circuits.
