STMicroelectronics recommends a PCB layout with a thermal pad 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 the device. Additionally, ensure good thermal design, use a heat sink if necessary, and avoid exceeding the maximum junction temperature (Tj) of 150°C.
The maximum allowed voltage on the input pins is 5V, but it's recommended to keep the input voltage below 4.5V to ensure reliable operation and prevent damage to the device.
The SM15T24AY has built-in ESD protection, but it's still recommended to follow proper ESD handling procedures during assembly and testing. Use an ESD wrist strap or mat, and ensure that the device is stored in an ESD-protected environment.
The recommended operating frequency range for the SM15T24AY is up to 100 kHz, but it can operate at higher frequencies with reduced performance and increased power consumption.
