Instructions for Use:

1. Forward Current (IF):

   • Ensure that the continuous forward current does not exceed 30 mA.
   • For pulse applications, do not exceed the peak forward current of 100 mA.

2. Reverse Voltage (VR):

   • Do not apply a reverse voltage greater than 7 V to avoid damaging the diode.

3. Temperature:

   • Operate the diode within the temperature range of -40掳C to 85掳C.
   • Store the diode within the temperature range of -55掳C to 150掳C.

4. Mounting:

   • Ensure proper heat dissipation if operating near the maximum current limits.
   • Follow standard PCB mounting practices to ensure reliable performance.

5. Handling:

   • Handle with care to avoid mechanical damage.
   • Use appropriate ESD protection to prevent damage from static electricity.

6. Testing:

   • Test the diode using a multimeter or a dedicated diode tester to ensure it is functioning correctly before installation.

7. Soldering:

   • Use a soldering iron with a temperature not exceeding 300掳C.
   • Solder the diode quickly to minimize thermal stress.

8. Storage:

   • Store in a dry, cool place to prevent moisture damage.
   • Keep in original packaging until ready for use to protect from environmental factors.
