SMF85A Frequently Asked Questions (FAQs)

  • The recommended PCB footprint for SMF85A is a rectangular pad with dimensions of 1.5mm x 0.8mm, with a 0.5mm radius corner. The pad should be centered on the component and have a solder mask defined around it.
  • While SMF85A is rated for operation up to 150°C, it's not recommended for use in high-temperature environments above 125°C without proper derating. Consult the manufacturer's application notes for guidance on high-temperature operation.
  • To ensure reliable soldering of SMF85A, use a soldering iron with a temperature of 250°C to 270°C, and apply a small amount of solder paste to the PCB pad. Avoid applying excessive force or pressure during soldering, as this can damage the component.
  • The maximum surge current rating for SMF85A is 100A for a 10/1000μs waveform. However, this rating may vary depending on the specific application and operating conditions. Consult the manufacturer's application notes for guidance on surge current rating.
  • Yes, SMF85A can be used in a parallel configuration to increase the overall current rating. However, it's essential to ensure that the components are properly matched and that the PCB design takes into account the increased current handling requirements.
