The recommended footprint and land pattern for the SMCJ18CA can be found in the Littelfuse application note AN9313, which provides guidelines for surface mount assembly of TVS diodes.
To ensure proper soldering, follow the recommended soldering profile and guidelines outlined in the Littelfuse application note AN9313. Additionally, use a soldering iron with a temperature range of 250°C to 260°C, and avoid applying excessive force or pressure during the soldering process.
The SMCJ18CA has an operating temperature range of -65°C to 150°C, as specified in the datasheet. However, it's essential to note that the device's performance and reliability may degrade if operated at extreme temperatures for extended periods.
While the SMCJ18CA is a high-quality TVS diode, it may not meet the specific requirements for high-reliability or aerospace applications. For such applications, it's recommended to consult with Littelfuse or a qualified representative to determine the suitability of the device and ensure compliance with relevant standards and regulations.
To prevent damage or degradation, handle the SMCJ18CA by the body, avoiding touching the leads or the glass passivated junction. Store the devices in their original packaging or in a dry, cool place, away from direct sunlight and moisture. Avoid exposing the devices to mechanical stress, extreme temperatures, or electrical overstress.
