STMicroelectronics recommends a PCB layout with a large copper area connected to the thermal pad, and multiple vias to dissipate heat efficiently. A minimum of 2oz copper thickness is recommended.
To ensure reliable operation at high temperatures, it's essential to follow the recommended thermal design guidelines, use a suitable heat sink, and ensure good airflow around the device. Additionally, consider derating the device's power dissipation according to the temperature derating curve provided in the datasheet.
Although the datasheet specifies the recommended operating conditions, it's essential to note that the maximum allowed voltage on the input pins is 5.5V, exceeding which can cause permanent damage to the device.
To protect the TN22-1500T from ESD, handle the device by the body or use an anti-static wrist strap, and ensure the PCB is designed with ESD protection in mind, such as using ESD diodes or resistors on the input pins.
STMicroelectronics recommends storing the TN22-1500T in a dry, cool place with a temperature range of -40°C to 125°C and a relative humidity of 60% or less to prevent moisture-related damage.
