The recommended footprint and land pattern for SMBJ188A can be found in the Littelfuse application note AN9313, which provides guidelines for PCB layout and assembly.
To select the correct TVS diode, consider factors such as the maximum voltage, current, and power rating required for your application. Also, consider the package type, operating temperature range, and response time. Littelfuse provides a TVS Diode Selection Guide that can help with the selection process.
The SMBJ188A is a specific part number in the SMBJ series, which offers a range of voltage and power ratings. The '188A' in the part number refers to the specific voltage rating (18.8V) and power rating (500W). Other parts in the SMBJ series have different voltage and power ratings, so it's essential to check the datasheet for the specific part number being used.
Yes, the SMBJ188A is qualified to AEC-Q101, which makes it suitable for automotive and high-reliability applications. However, it's essential to review the specific requirements of your application and ensure that the SMBJ188A meets those requirements.
Follow the recommended soldering and assembly guidelines provided in the Littelfuse application note AN9313. This includes using a soldering iron with a temperature range of 250°C to 260°C, and ensuring the PCB is designed with a suitable land pattern and thermal relief.
