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 or a dedicated heat sink.
To ensure reliable operation in high-temperature environments, it's essential to follow the recommended derating curves for the device. Additionally, consider using a heat sink or thermal interface material to reduce the junction temperature. ROHM also recommends using a thermally conductive PCB material and ensuring good airflow around the device.
Although the datasheet specifies the recommended operating voltage range, it's essential to note that the absolute maximum rating for the input pins is 6V. Exceeding this voltage can cause permanent damage to the device.
ROHM recommends using ESD protection devices, such as TVS diodes or ESD arrays, on the input lines to protect the UCR18EVHFSR033 from electrostatic discharge. Additionally, follow proper handling and storage procedures to prevent ESD damage.
ROHM recommends a soldering profile with a peak temperature of 260°C (500°F) and a dwell time of 10-30 seconds. It's essential to follow the recommended soldering profile to prevent damage to the device.
