A thermal pad on the bottom of the package should be connected to a large copper area on the PCB to dissipate heat efficiently. The copper area should be at least 1 inch x 1 inch in size and should be connected to a ground plane to reduce thermal resistance.
To ensure reliability, operate the device within the recommended temperature range (up to 150°C). Use a heat sink or thermal interface material to reduce the junction temperature. Also, ensure that the device is soldered correctly to prevent thermal resistance increase.
The maximum allowable voltage is 1200V, but it's recommended to derate the voltage to 1000V to ensure long-term reliability and to prevent electrical overstress.
Use a voltage clamp or a transient voltage suppressor (TVS) to limit voltage transients. Also, ensure that the device is operated within the recommended voltage range and that the PCB is designed to minimize electromagnetic interference (EMI).
Store the devices in a dry, cool place (less than 30°C and 60% relative humidity). Use a moisture barrier bag or a dry pack to prevent moisture absorption. Avoid exposing the devices to direct sunlight or high temperatures during storage.
