The recommended footprint and land pattern for the TPSMB43CA 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 the TPSMB43CA 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 resistance.
Yes, the TPSMB43CA is AEC-Q101 qualified, which means it meets the stringent requirements for reliability and performance 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 TPSMB43CA variant, consider the following factors: voltage rating, power rating, and package type. Consult the datasheet and Littelfuse's selection guide to determine the most suitable variant for your application.
The TPSMB43CA provides ESD protection up to ±30kV air discharge and ±30kV contact discharge, according to the IEC 61000-4-2 standard. This makes it suitable for protecting sensitive electronics from ESD events.
