The recommended footprint and land pattern for SMAJ70A 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 SMAJ70A 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, SMAJ70A 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 SMAJ70A 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.
The recommended soldering profile for SMAJ70A is a peak temperature of 260°C for 10-15 seconds, with a ramp-up rate of 3°C/second and a ramp-down rate of 6°C/second. Consult the Littelfuse application note AN9313 for more information.
