The recommended footprint and land pattern for the SMBJ350CA can be found in the Littelfuse application note AN9313, which provides guidelines for surface mount assembly of TVS diodes.
To ensure proper soldering, follow the recommended soldering profile and guidelines outlined in the Littelfuse application note AN9313. Additionally, use a soldering iron with a temperature range of 250°C to 260°C, and avoid applying excessive force or pressure during the soldering process.
The SMBJ350CA has an operating temperature range of -65°C to 150°C, as specified in the datasheet. However, it's essential to note that the device's performance and reliability may degrade if operated at extreme temperatures for extended periods.
While the SMBJ350CA is a high-quality TVS diode, it may not meet the specific requirements for high-reliability or aerospace applications. For such applications, it's recommended to consult with Littelfuse or consider using a more specialized TVS diode, such as the SP350, which is designed for high-reliability applications.
To select the correct SMBJ350CA variant, consider factors such as the required standoff voltage, peak pulse current, and package type. Consult the datasheet and application notes to determine the most suitable variant for your specific application.
