The recommended footprint and land pattern for SMBJ17A-E3/5B can be found in the Vishay Intertechnologies application note AN10365, 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. Consult the datasheet and application notes for guidance.
The main difference between SMBJ17A-E3/5B and other SMBJxxA-E3/5B devices is the breakdown voltage (VBR) and the clamping voltage (VC). The 'xx' in the part number represents the voltage rating, with higher numbers indicating higher voltage ratings.
The SMBJ17A-E3/5B is rated for operation up to 150°C, but derating may be necessary for high-temperature applications. Consult the datasheet and application notes for guidance on high-temperature operation.
To ensure reliability and longevity, follow proper PCB design and assembly guidelines, ensure proper voltage and current ratings, and consider environmental factors such as temperature and humidity. Also, consider using a TVS diode with a high surge capability and a low clamping voltage.
