1SMA78CAT3G Frequently Asked Questions (FAQ)

  • The recommended footprint and land pattern for the 1SMA78CAT3G can be found in the Littelfuse application note AN9313, which provides guidelines for surface mount assembly of TVS diodes.

  • To select the correct TVS diode, consider factors such as the maximum voltage, current, and power rating required for your application. You should also consider the clamping voltage, response time, and capacitance of the TVS diode. Littelfuse provides a TVS Diode Selection Guide that can help with this process.

  • A unidirectional TVS diode protects against overvoltage in one direction, while a bidirectional TVS diode protects against overvoltage in both directions. The 1SMA78CAT3G is a unidirectional TVS diode, which means it is designed to protect against positive overvoltage surges.

  • Yes, the 1SMA78CAT3G is qualified to AEC-Q101 standards, which makes it suitable for use in high-reliability and automotive applications. However, it's essential to review the specific requirements of your application and ensure that the TVS diode meets those requirements.

  • Follow the recommended soldering and assembly guidelines provided in the Littelfuse application note AN9313. This includes using a soldering iron with a temperature of 250°C to 260°C, and ensuring that the TVS diode is properly aligned and seated on the PCB.
