The recommended footprint and land pattern for SMAJ20A 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 SMAJ20A 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, SMAJ20A 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 SMAJ20A variant, consider the following factors: breakdown voltage, clamping voltage, and power rating. Choose a variant that meets the specific requirements of your application, and consult the datasheet and application notes for guidance.
SMAJ20A provides ESD protection up to ±30kV according to the IEC 61000-4-2 standard. However, the actual ESD protection capability may vary depending on the application and PCB layout. Consult the datasheet and application notes for more information.
