1N5349B Frequently Asked Questions (FAQs)

  • The recommended operating temperature range for the 1N5349B is -65°C to 175°C.
  • To ensure proper biasing, the 1N5349B should be connected in a circuit with a voltage source, a current-limiting resistor, and a load. The voltage source should be set to the recommended operating voltage, and the current-limiting resistor should be chosen to limit the current to the recommended maximum value.
  • The maximum surge current rating for the 1N5349B is 100A for a duration of 1ms.
  • To protect the 1N5349B from overvoltage and overcurrent conditions, a voltage regulator or a transient voltage suppressor (TVS) can be used to limit the voltage and current to the recommended maximum values.
  • The typical junction-to-case thermal resistance of the 1N5349B is 1.5°C/W.
