The recommended footprint and land pattern for the 5.0SMDJ90A 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 5.0SMDJ90A 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 5.0SMDJ90A is AEC-Q101 qualified, which means it meets the stringent requirements for automotive applications. However, it is recommended to consult with Littelfuse or a qualified engineer to ensure that the device meets the specific requirements of the application.
To select the correct TVS diode, consider the following factors: voltage rating, peak pulse current, clamping voltage, and response time. Consult the Littelfuse TVS Diode Selection Guide or consult with a qualified engineer to ensure the correct device is selected for the specific application.
The 5.0SMDJ90A should be stored in a dry, cool place, away from direct sunlight and moisture. Handling should be done with anti-static precautions, and the device should be soldered within the recommended temperature range to prevent damage.
