SMAJ250A Frequently Asked Questions (FAQ)
-
The recommended footprint and land pattern for SMAJ250A 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 SMAJ250A 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, SMAJ250A can be used in a parallel configuration to increase the power rating. However, it is essential to ensure that the devices are matched in terms of their electrical characteristics and that the PCB is designed to minimize current imbalance between the devices.
-
The maximum allowable voltage transients for SMAJ250A are specified in the datasheet as 250A, 8/20μs waveform. However, it is recommended to consult the Littelfuse application note AN9764 for more information on voltage transient protection using SMAJ250A.
-
To select the correct SMAJ250A device, consider the following factors: working voltage, peak pulse current, and package type. Consult the Littelfuse selection guide or consult with a Littelfuse application engineer for assistance.
