The recommended footprint and land pattern for the SMCJ48CA can be found in the Littelfuse application note AN9313, which provides guidelines for surface mount assembly of TVS diodes.
To ensure proper soldering and avoid defects, follow the recommended soldering profile and guidelines outlined in the Littelfuse application note AN9313, and use a solder with a melting point below 260°C.
The maximum operating temperature range for the SMCJ48CA is -65°C to 150°C, as specified in the datasheet. However, it's recommended to derate the device's power handling capability at higher temperatures to ensure reliable operation.
While the SMCJ48CA is a high-quality TVS diode, it may not meet the specific requirements for high-reliability or aerospace applications. For such applications, consider using a device that is specifically designed and qualified for those markets, such as the Littelfuse SP0723 or SP0724.
To select the correct TVS diode, consider factors such as the maximum voltage, current, and power handling requirements of your application, as well as the desired level of protection and response time. Consult the Littelfuse TVS diode selection guide or contact a Littelfuse application engineer for guidance.
