ROHM recommends a thermal pad size of at least 2.5mm x 2.5mm with multiple vias to the ground plane to ensure good heat dissipation. Additionally, keeping the PCB layer stack-up symmetrical and using a thermal relief pattern around the thermal pad can help reduce thermal resistance.
To ensure reliable operation in high-temperature environments, it's essential to follow proper thermal design guidelines, such as providing adequate heat sinking, using a suitable thermal interface material, and keeping the device within its recommended operating temperature range (up to 125°C for the KTR03EZPF2000).
ROHM recommends a soldering profile with a peak temperature of 260°C, a dwell time above 240°C of 30-60 seconds, and a total process time of 60-120 seconds. It's also essential to follow the recommended soldering conditions and handling precautions to prevent damage to the device.
To prevent damage during storage and shipping, it's recommended to store the devices in their original packaging, avoid exposing them to high temperatures or humidity, and handle them with care to prevent mechanical stress or electrostatic discharge.
To prevent electrostatic discharge (ESD) damage, it's recommended to handle the devices with an anti-static wrist strap or mat, use ESD-protected packaging, and follow proper ESD handling procedures during assembly and testing.
