The recommended footprint and land pattern for the 3.0SMCJ33A can be found in the Littelfuse application note AN9313, which provides guidelines for surface mount assembly of SMCJ series TVS diodes.
To ensure proper soldering and reliability, follow the recommended soldering profile and guidelines outlined in the Littelfuse application note AN9313, and ensure that the soldering process meets the requirements of IPC J-STD-020.
The 3.0SMCJ33A is rated for operation up to 150°C, but its performance may degrade at high temperatures. For high-temperature applications, consider using a TVS diode with a higher temperature rating, such as the 3.0SMCJ33A-HR, which is rated for operation up to 175°C.
To select the correct TVS diode, consider the following factors: voltage rating, peak pulse current, clamping voltage, and response time. Use the Littelfuse TVS Diode Selection Guide or consult with a Littelfuse application engineer to determine the best TVS diode for your specific application.
The 3.0SMCJ33A and 3.0SMCJ33CA are both TVS diodes with the same voltage and current ratings, but the 3.0SMCJ33CA has a higher surge capability and is designed for more demanding applications. The 3.0SMCJ33CA also has a slightly different package design and is RoHS-compliant.
