Instructions for Use

1. Mounting:

   • Ensure proper heat sinking to maintain the junction temperature within the specified range.
   • Use a thermal compound between the device and the heatsink to improve thermal conductivity.

2. Gate Triggering:

   • Apply a gate current greater than the maximum gate trigger current (Igt) to turn on the SCR.
   • Once triggered, the SCR will remain on as long as the anode current exceeds the holding current (Ih).

3. Surge Handling:

   • The SCR can handle non-repetitive surge currents up to 200 A for 8.3 ms. Ensure that surge conditions do not exceed these limits to avoid damage.

4. Overvoltage Protection:

   • Use appropriate overvoltage protection circuits to prevent damage from voltage spikes exceeding the maximum repetitive peak reverse voltage (Vdrm).

5. Thermal Management:

   • Monitor the junction temperature (Tj) to ensure it does not exceed 125掳C. Proper cooling is essential, especially under high current conditions.

6. Storage:

   • Store the device in a dry environment with temperatures between -65掳C and 150掳C to prevent degradation.

7. Handling:

   • Handle the device with care to avoid mechanical stress, which can affect performance and reliability.

8. Testing:

   • Test the device in a controlled environment to ensure it meets the specified parameters before integrating it into the final application.
