The recommended footprint and land pattern for the SMBJ33CA-HR 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 any specific certifications or compliance requirements.
The SMBJ33CA-HR is a high-reliability version of the SMBJ series TVS diodes, with a higher surge current rating and tighter voltage tolerance. It is designed for high-reliability applications such as aerospace, defense, and medical devices.
The SMBJ33CA-HR is rated for operation up to 150°C, but its performance may degrade at high temperatures. Consult the datasheet and application notes for guidance on using the device in high-temperature environments.
Follow the recommended soldering and assembly guidelines in the Littelfuse application note AN9313, and ensure that the PCB is designed with adequate thermal relief and clearance around the device.
