SMBJ18A Frequently Asked Questions (FAQs)

  • The recommended footprint and land pattern for the SMBJ18A can be found in the Littelfuse application note AN9313, which provides guidelines for surface mount assembly of TVS diodes.
  • To select the correct SMBJ18A variant, consider the working voltage, peak pulse current, and clamping voltage required for your application. Refer to the datasheet and consult with a Littelfuse application engineer if needed.
  • The maximum operating temperature for the SMBJ18A is 150°C, as specified in the datasheet. However, it's recommended to derate the device's power handling capability at higher temperatures to ensure reliable operation.
  • While the SMBJ18A is primarily designed for transient voltage suppression, it can be used in high-frequency applications up to 1 GHz. However, the device's parasitic capacitance and inductance should be considered in the design.
  • Follow the recommended soldering profile and assembly guidelines provided in the Littelfuse application note AN9313 to ensure reliable and consistent assembly of the SMBJ18A.
