SMF20A Frequently Asked Questions (FAQs)

  • The recommended footprint and land pattern for SMF20A 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 SMF20A according to the temperature derating curve provided in the datasheet. Additionally, ensure that the device is soldered correctly and that the PCB is designed to handle high temperatures.
  • Yes, SMF20A can be used in a parallel configuration to increase the power rating. However, it is essential to ensure that the devices are matched in terms of their electrical characteristics and that the PCB is designed to handle the increased current and power.
  • The maximum surge current that SMF20A can handle is 20A, as specified in the datasheet. However, it is recommended to derate the surge current according to the pulse width and repetition rate of the surge.
  • Yes, SMF20A is compatible with lead-free soldering processes. Littelfuse ensures that their devices meet the requirements of the RoHS directive and are compatible with lead-free soldering processes.
