Instructions for Use:

  1. Mounting:

    • Ensure that the diode is mounted in a way that it can dissipate heat effectively, especially when operating near its maximum power dissipation.
    • Avoid mechanical stress on the leads during soldering or handling.
  2. Soldering:

    • Use a temperature-controlled soldering iron and keep the soldering time as short as possible to prevent thermal damage.
    • Soldering temperature should not exceed 300°C and the duration should be less than 10 seconds.
  3. Electrical Connections:

    • Connect the cathode (shorter lead or banded end) to the positive side of the circuit and the anode (longer lead) to the negative side.
    • Ensure that the reverse voltage does not exceed the maximum rated value to avoid breakdown.
  4. Thermal Management:

    • If the diode will be operating at high current levels, consider using a heat sink to improve thermal performance.
    • Monitor the junction temperature to ensure it stays within the specified range.
  5. Storage:

    • Store the diodes in a dry, cool place away from direct sunlight and corrosive environments.
    • Handle with care to avoid physical damage to the glass body.
  6. Testing:

    • Before installing the diode in a circuit, test it with a multimeter to ensure it is functioning correctly.
    • Check for proper forward and reverse characteristics according to the specifications provided.
