The recommended footprint and land pattern for the 1.5SMC18A 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 1.5SMC18A is -65°C to 150°C, as specified in the datasheet. However, it's recommended to derate the device's power rating at higher temperatures to ensure reliable operation.
Yes, the 1.5SMC18A is suitable for high-reliability applications, such as aerospace or automotive, due to its high surge capability, low leakage current, and high reliability ratings. However, it's essential to follow the recommended qualification and testing procedures for these applications.
To select the correct TVS diode, consider factors such as the maximum voltage, current, and power requirements of your application, as well as the desired level of protection and response time. Consult the Littelfuse TVS diode selection guide or consult with a Littelfuse application engineer for guidance.
