The recommended footprint and land pattern for SMBJ36A-Q can be found in the Bourns Application Note AN164, 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 the selection process.
The main difference between SMBJ36A-Q and SMBJ36CA-Q is the AEC-Q101 qualification. SMBJ36CA-Q is AEC-Q101 qualified, which means it meets the automotive industry's standards for reliability and performance. SMBJ36A-Q is not AEC-Q101 qualified, but still meets the industry standards for TVS diodes.
The SMBJ36A-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 TVS diode or consulting with a Bourns application engineer.
To ensure the reliability of SMBJ36A-Q, follow proper PCB layout and assembly guidelines, ensure proper voltage and current ratings, and consider using a TVS diode with a built-in thermal protection device (TPD). Additionally, perform thorough testing and validation of your design to ensure it meets the required specifications.
