Instructions for Use:

  1. Handling:

    • Handle with care to avoid damage to the diode.
    • Use appropriate ESD (Electrostatic Discharge) precautions.
  2. Soldering:

    • Preheat the board to 100°C to 150°C.
    • Soldering temperature should not exceed 260°C.
    • Soldering time should be limited to 10 seconds.
  3. Mounting:

    • Ensure the diode is placed correctly on the PCB according to the polarity markings.
    • Apply sufficient pressure to ensure good contact between the diode and the PCB.
  4. Storage:

    • Store in a dry, cool place.
    • Avoid exposure to high humidity and extreme temperatures.
  5. Testing:

    • Use a multimeter to test the diode before installation.
    • Ensure the diode is not shorted or open.
  6. Circuit Design:

    • Ensure the circuit design does not exceed the maximum power dissipation and operating temperature range.
    • Use appropriate heat sinks if necessary to manage thermal dissipation.
  7. Compliance:

    • Ensure compliance with all relevant safety and regulatory standards.
