SMF15A Frequently Asked Questions (FAQs)

  • The recommended footprint and land pattern for SMF15A can be found in the Littelfuse application note AN9313, which provides guidelines for surface mount assembly of TVS diodes.
  • To ensure reliability in high-temperature applications, it is recommended to derate the power rating of SMF15A according to the temperature derating curve provided in the datasheet. Additionally, ensure that the device is properly soldered and that the PCB is designed to minimize thermal resistance.
  • Yes, SMF15A can be used in a parallel configuration to increase the power rating. However, it is essential to ensure that the devices are properly matched and that the current sharing is even to avoid overheating and reduce reliability.
  • The maximum allowable voltage transients for SMF15A are specified in the datasheet as 15kV for a 10/1000μs waveform. However, it is recommended to consult with Littelfuse application engineers for specific guidance on voltage transient requirements.
  • To select the correct SMF15A variant, consider the working voltage, peak pulse current, and clamping voltage requirements of your application. Consult the datasheet and application notes to determine the most suitable variant for your specific use case.
