The recommended footprint and land pattern for the TPSMB33CA-VR 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 TPSMB33CA-VR according to the temperature derating curve provided in the datasheet. Additionally, ensure that the device is properly soldered and that the PCB is designed to handle the thermal stresses.
While the TPSMB33CA-VR is designed for standard voltage applications, it can be used in non-standard voltage applications with caution. However, it is essential to consult with Littelfuse application engineers to ensure that the device can handle the specific voltage requirements and to discuss any necessary modifications or custom designs.
The TPSMB33CA-VR has an ESD rating of ±30kV, which is sufficient for most industrial and commercial applications. However, if your application requires a higher ESD rating, you may need to consider a different device or consult with Littelfuse application engineers for custom solutions.
To select the correct TPSMB33CA-VR variant, consider the following factors: voltage rating, power rating, and package type. Consult the datasheet and application notes to determine the most suitable variant for your specific application.
