2N4399 Frequently Asked Questions (FAQ)

  • The recommended operating temperature range for the 2N4399 is -55°C to +150°C, although it can withstand storage temperatures from -65°C to +200°C.

  • To ensure proper biasing, the 2N4399 requires a VCC supply voltage between 3V and 18V, and a VEE supply voltage between -3V and -18V. The recommended bias current is 1mA to 10mA.

  • The maximum power dissipation for the 2N4399 is 1W, and it is recommended to derate the power dissipation by 8.33mW/°C above 25°C to ensure reliable operation.

  • Yes, the 2N4399 can be used as a switch, but it is not recommended due to its relatively high on-state resistance (typically 50 ohms) and limited current handling capability (up to 100mA).

  • To protect the 2N4399 from ESD, it is recommended to handle the device with anti-static precautions, such as using an anti-static wrist strap or mat, and to ensure that the device is properly grounded during handling and assembly.
