The recommended footprint and land pattern for the 1.5SMB43CA can be found in the Littelfuse application note AN9313, which provides guidelines for surface mount assembly of SMB packages.
To ensure proper soldering, follow the recommended soldering profile and temperature guidelines provided in the Littelfuse application note AN9313. Additionally, use a solder with a melting point below 260°C to prevent damage to the component.
The maximum allowable voltage derating for the 1.5SMB43CA is typically 10-15% below the rated voltage, depending on the specific application and environmental conditions. Consult with a Littelfuse application engineer for specific guidance.
The 1.5SMB43CA is rated for operation up to 150°C, but its performance may degrade at higher temperatures. For high-temperature applications above 150°C, consider using a different TVS diode with a higher temperature rating, such as the 1.5SMB43CA-HR.
To select the correct TVS diode, consider factors such as the maximum voltage, current, and power requirements of your application, as well as the desired level of protection and response time. Consult with a Littelfuse application engineer or use the Littelfuse TVS Diode Selection Guide to determine the most suitable device for your needs.
