A good PCB layout for the SM15T100A involves keeping the input and output traces separate, using a ground plane, and placing the device close to the power source. Additionally, using a shielded cable and a common-mode choke can help reduce EMI.
To ensure proper cooling, make sure the SM15T100A is mounted on a heat sink with a thermal resistance of less than 10°C/W. Also, ensure good airflow around the device and avoid blocking the airflow with other components.
The maximum allowed voltage transient for the SM15T100A is 1.5 times the maximum rated voltage, but not exceeding 1500V. However, it's recommended to limit the voltage transient to 1.2 times the maximum rated voltage to ensure reliable operation.
Yes, the SM15T100A is suitable for high-reliability applications. It's designed and manufactured according to STMicroelectronics' high-reliability standards, and it's also qualified according to the AEC-Q101 standard for automotive applications.
When selecting a capacitor for the SM15T100A, consider the voltage rating, capacitance value, and ESR (Equivalent Series Resistance). A capacitor with a voltage rating of at least 1.5 times the maximum rated voltage, a capacitance value of 10nF to 100nF, and an ESR of less than 1 ohm is recommended.
