1N4745A Frequently Asked Questions (FAQs)

  • The recommended operating temperature range for the 1N4745A is -65°C to +175°C.
  • To ensure stable zener operation, the 1N4745A should be biased with a minimum current of 1 mA and a maximum current of 30 mA, and the voltage across the diode should be within the specified zener voltage range.
  • The maximum power dissipation for the 1N4745A is 1.3 watts at a lead temperature of 25°C.
  • While the 1N4745A can be used as a voltage regulator, it is not recommended due to its limited current handling capability and potential for thermal runaway. A dedicated voltage regulator IC is recommended for most applications.
  • To protect the 1N4745A from overvoltage and ESD, use a voltage limiter or a transient voltage suppressor (TVS) in parallel with the diode, and ensure that the device is handled and stored in an ESD-safe environment.
