The recommended footprint and land pattern for SMBJ7.0A-Q can be found in the Bourns Application Note S-8153, 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 clamping voltage, response time, and capacitance of the TVS diode. Bourns provides a TVS Diode Selection Guide that can help with this process.
The main difference between SMBJ7.0A-Q and SMBJ7.0CA-Q is the AEC-Q101 qualification. SMBJ7.0CA-Q is AEC-Q101 qualified, which means it meets the automotive industry's standards for reliability and performance. SMBJ7.0A-Q is not AEC-Q101 qualified, but still meets the standard specifications for TVS diodes.
The SMBJ7.0A-Q is rated for operation up to 150°C, but its performance may degrade at high temperatures. If your application requires operation above 125°C, consider using a high-temperature-rated TVS diode or consulting with a Bourns application engineer.
To ensure reliability, follow proper PCB layout and assembly guidelines, and consider factors such as voltage derating, current handling, and thermal management. Also, perform thorough testing and validation of your design to ensure it meets the required specifications.
