Instructions for Use:

1. Mounting:

   • Ensure proper heat dissipation if operating near maximum current.
   • Use appropriate mounting techniques to avoid mechanical stress on the leads.

2. Soldering:

   • Preheat the PCB to reduce thermal shock.
   • Solder within the temperature range of 260°C for no more than 10 seconds.
   • Allow the component to cool naturally after soldering.

3. Electrical Connections:

   • Connect the anode (A) to the positive side of the circuit.
   • Connect the cathode (K) to the negative side of the circuit.
   • Ensure that the reverse voltage does not exceed 20V to prevent breakdown.

4. Surge Handling:

   • The diode can handle non-repetitive surge currents up to 30A for short durations (10 ms half sine wave).
   • For repetitive surges, ensure the peak current is within the rated average rectified forward current.

5. Thermal Management:

   • Monitor the junction temperature to ensure it remains within the operating range (-40°C to 150°C).
   • Use heatsinks or other cooling methods if necessary, especially in high-power applications.

6. Storage:

   • Store in a dry, cool place with temperatures between -65°C and 150°C.
   • Avoid exposure to corrosive environments.

7. Handling:

   • Handle with care to avoid damage to the leads and body.
   • Use anti-static precautions to prevent electrostatic discharge damage.

8. Testing:

   • Test the diode using a multimeter or diode tester to ensure proper functionality.
   • Check for continuity from anode to cathode and ensure no continuity in reverse direction.
