Instructions for Use:

1. Mounting: Ensure proper heat dissipation if operating near maximum power or temperature limits.
2. Polarity: Pay attention to the polarity of the diode; incorrect installation can lead to immediate failure.
3. Handling: Handle with care to avoid damage from electrostatic discharge (ESD).
4. Soldering: Use a temperature-controlled soldering iron and do not exceed soldering temperatures above 260掳C for more than 10 seconds.
5. Testing: Verify correct operation after installation by checking forward and reverse characteristics.
6. Storage: Store in a dry, cool place away from direct sunlight and corrosive environments.
