The recommended footprint and land pattern for the 1.5SMBJ12CA-H can be found in the Bourns application note AN144, 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. You should 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 1.5SMBJ12CA-H and the 1.5SMBJ12A-H is the AEC-Q101 qualification. The 1.5SMBJ12CA-H is AEC-Q101 qualified, which means it meets the stringent requirements for automotive applications, whereas the 1.5SMBJ12A-H is not AEC-Q101 qualified.
Yes, the 1.5SMBJ12CA-H can be used in non-automotive applications. Although it is AEC-Q101 qualified, it can still be used in other applications that require a high-reliability TVS diode.
The maximum operating temperature range for the 1.5SMBJ12CA-H is -55°C to +150°C, as specified in the datasheet.
