Instructions for Use:

1. Forward Voltage (V_F):

   • Ensure that the forward voltage across the diode does not exceed 1.8V when the forward current is 500 mA.

2. Reverse Voltage (V_R):

   • The maximum reverse voltage should not exceed 500V to prevent breakdown.

3. Forward Current (I_F):

   • The maximum continuous forward current should not exceed 1000 mA. For pulse applications, ensure the current does not exceed this value for extended periods to avoid overheating.

4. Reverse Current (I_R):

   • The reverse leakage current should be kept below 100 渭A at a reverse voltage of 500V to maintain optimal performance.

5. Power Dissipation (P_T):

   • The maximum power dissipation is 2000 mW. Ensure adequate heat sinking if operating near this limit to prevent thermal damage.

6. Operating Junction Temperature (T_J):

   • The operating junction temperature should be within the range of -40掳C to 125掳C to ensure reliable operation.

7. Storage Temperature (T_S):

   • Store the diode in an environment with temperatures ranging from -55掳C to 150掳C to prevent damage.

8. Thermal Resistance (R_胃JC):

   • The thermal resistance from the junction to the case is 5掳C/W. Use appropriate cooling methods to manage heat dissipation effectively.

Handling and Storage:

• Handle the diode with care to avoid mechanical damage.
• Store in a dry, cool place to prevent moisture damage.
• Avoid exposing the diode to extreme temperatures or corrosive environments.

Mounting:

• Ensure proper mounting to maintain good thermal contact and prevent mechanical stress.
• Use appropriate soldering techniques and avoid excessive heat during soldering to prevent damage to the diode.
