Instructions:

1. Mounting:

   • Ensure the diode is mounted with adequate heat dissipation if operating near its maximum power rating.
   • Use a heatsink if necessary to maintain the junction temperature within the specified range.

2. Soldering:

   • Preheat the PCB to reduce thermal shock.
   • Solder quickly to avoid exceeding the maximum soldering temperature of 260掳C for more than 10 seconds.

3. Storage:

   • Store in a dry, cool place away from direct sunlight.
   • Handle with care to avoid mechanical damage.

4. Electrical Connection:

   • Connect the cathode (shorter lead or marked side) to the positive voltage and the anode (longer lead or unmarked side) to the negative voltage.
   • Ensure the reverse voltage does not exceed the Zener voltage to prevent damage.

5. Testing:

   • Test the diode using a multimeter set to the diode test mode.
   • The forward voltage should be around 1.0V, and the reverse resistance should be high.

6. Safety:

   • Always disconnect the power supply before making any changes to the circuit.
   • Use appropriate personal protective equipment (PPE) when handling electrical components.
