The recommended footprint and land pattern for SMAJ30A 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 SMAJ30A 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 stress.
Yes, SMAJ30A 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 SMAJ30A variant, consider the following factors: working voltage, peak pulse current, and package type. Consult the datasheet and Littelfuse's selection guide to determine the most suitable variant for your application.
The SMAJ30A has an ESD rating of Class 3A (>2500 V) per IEC 61000-4-2, which means it can withstand electrostatic discharges up to 2500 V.
