SMBJ78A Frequently Asked Questions (FAQs)

  • The recommended footprint and land pattern for the SMBJ78A can be found in the Littelfuse application note AN9313, which provides guidelines for surface mount assembly of TVS diodes.
  • To select the correct SMBJ78A variant, consider the working voltage, peak pulse current, and clamping voltage required for your application. Refer to the datasheet and consult with a Littelfuse representative if needed.
  • The maximum operating temperature for the SMBJ78A is 150°C, as specified in the datasheet. However, it's recommended to derate the device's performance at higher temperatures to ensure reliable operation.
  • The SMBJ78A is designed for transient voltage suppression and is not optimized for high-frequency applications. For high-frequency applications, consider using a different TVS diode or consulting with a Littelfuse representative for guidance.
  • Follow the recommended soldering and assembly guidelines outlined in the Littelfuse application note AN9313 to ensure proper assembly and minimize the risk of damage or failure.
