The recommended footprint and land pattern for the SMBJ22A-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 this process.
The main difference between the SMBJ22A-Q and other SMBJxxA-Q devices is the breakdown voltage (VBR) and the clamping voltage (VC). The SMBJ22A-Q has a VBR of 22V and a VC of 31.4V, while other devices in the series have different VBR and VC ratings. Choose the device that best matches your application's voltage requirements.
The SMBJ22A-Q is rated for operation up to 150°C, but its performance may degrade at high temperatures. Consult the datasheet and Bourns' reliability data for more information on high-temperature operation.
Follow the recommended soldering and assembly procedures outlined in the Bourns Application Note AN164. Ensure proper soldering temperature, time, and technique to avoid damaging the device.
