The recommended footprint and land pattern for the 1.5SMBJ58A can be found in the Bourns application note 'SMB and SMC Footprint and Land Pattern' (document number 31211).
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 (e.g. automotive, industrial, etc.).
The main difference between the 1.5SMBJ58A and the 1.5SMCJ58A is the package type. The 1.5SMBJ58A is in a SMB (DO-214AA) package, while the 1.5SMCJ58A is in a SMC (DO-214AB) package. The SMC package is slightly larger than the SMB package, but both devices have the same electrical characteristics.
The 1.5SMBJ58A is a commercial-grade device, but Bourns also offers high-reliability and high-temperature versions of the device, such as the 1.5SMBJ58AHF (high-reliability) and the 1.5SMBJ58AT3G (high-temperature). Consult the Bourns website or contact a Bourns representative for more information.
Follow the recommended soldering and assembly procedures outlined in the Bourns application note 'Soldering and Assembly Guidelines for Bourns Surge Protective Devices' (document number 31212).
