ROHM recommends a thermal pad on the bottom of the package, connected to a large copper area on the PCB to dissipate heat efficiently. A minimum of 2oz copper thickness is recommended, and the thermal pad should be connected to a ground plane to reduce thermal resistance.
To ensure reliable operation at high temperatures, it's essential to follow the recommended derating curves for voltage and current, and to ensure that the device is operated within the specified temperature range. Additionally, consider using a heat sink or thermal management system to keep the device temperature below 125°C.
ROHM recommends a soldering profile with a peak temperature of 260°C, a dwell time of 10-30 seconds, and a cooling rate of 3-5°C/s. It's also important to use a solder with a melting point above 217°C to ensure reliable connections.
To prevent electrostatic discharge (ESD) damage, handle the device by the body or pins, and avoid touching the pins or die. Use an ESD wrist strap or mat, and ensure that the PCB and assembly process are ESD-compliant. Additionally, consider adding ESD protection devices, such as TVS diodes, to the circuit.
Store the device in a dry, cool place, away from direct sunlight and moisture. The recommended storage temperature range is -40°C to 125°C, and the relative humidity should be below 60%. Avoid storing the device in a location with high levels of pollution or contamination.
