The recommended footprint and land pattern for SMAJ18CA can be found in the Littelfuse application note AN9313, which provides guidelines for surface mount assembly of TVS diodes.
To ensure reliability in high-temperature applications, it is recommended to derate the power rating of SMAJ18CA according to the temperature derating curve provided in the datasheet. Additionally, ensure that the device is soldered correctly and that the PCB is designed to minimize thermal resistance.
Yes, SMAJ18CA is AEC-Q101 qualified, which means it meets the stringent requirements for automotive applications. However, it is recommended to consult with Littelfuse's automotive support team to ensure that the device meets the specific requirements of your application.
To select the correct SMAJ18CA variant, consider the following factors: voltage rating, peak pulse current, and package type. Consult the datasheet and Littelfuse's selection guide to determine the most suitable variant for your application.
To prevent damage and ensure reliability, store SMAJ18CA in a dry, cool place, away from direct sunlight and moisture. Handle the devices by the body, avoiding touching the leads or die. Follow the guidelines outlined in the Littelfuse application note AN9312 for proper storage and handling of TVS diodes.
