The recommended footprint and land pattern for SMAJ28CA 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 SMAJ28CA according to the temperature derating curve provided in the datasheet. Additionally, ensure that the device is operated within the recommended storage temperature range of -55°C to 150°C.
Yes, SMAJ28CA is qualified to the AEC-Q101 standard, which makes it suitable for use in automotive applications. However, it is recommended to consult with Littelfuse's automotive support team to ensure that the device meets the specific requirements of the application.
To select the correct SMAJ28CA variant, consider the following factors: voltage rating, power rating, and package type. The datasheet provides a selection guide that can help in choosing the correct variant based on the application requirements.
SMAJ28CA provides ESD protection up to ±30kV air discharge and ±30kV contact discharge, as per the IEC 61000-4-2 standard. This makes it suitable for use in applications that require protection against electrostatic discharge.
