Instructions for Use:

1. Mounting:

   • Ensure the diode is mounted with proper heat sinking if operating near maximum power dissipation.
   • Avoid mechanical stress on the leads.

2. Biasing:

   • Apply the Zener voltage in reverse bias to achieve the desired regulation.
   • Ensure the current through the diode is within the specified range (Izt to Izm).

3. Temperature Considerations:

   • Operate within the specified temperature range to ensure reliable performance.
   • For extended life, avoid prolonged operation at the upper limits of the temperature range.

4. Storage:

   • Store in a dry environment within the storage temperature range to prevent damage.

5. Handling:

   • Handle with care to avoid damaging the leads or the body of the diode.
   • Use appropriate ESD (Electrostatic Discharge) precautions to prevent damage.

6. Testing:

   • Use a constant current source to test the Zener voltage.
   • Measure the voltage across the diode while it is under the test current (Izt).
