1SMA28AT3G Frequently Asked Questions (FAQs)

  • The recommended footprint and land pattern for the 1SMA28AT3G can be found in the onsemi application note AND8308/D, which provides guidelines for surface mount assembly of onsemi's DO-214AC (SMA) package.
  • To ensure reliability in high-temperature applications, it is essential to follow the recommended derating curves for the 1SMA28AT3G, as specified in the datasheet. Additionally, consider using a heat sink or thermal interface material to reduce the junction temperature.
  • While the 1SMA28AT3G is primarily designed for low-frequency applications, it can be used in high-frequency applications up to 1 GHz. However, the device's performance may degrade at higher frequencies due to parasitic inductance and capacitance. It is recommended to consult with onsemi's application engineers for specific guidance.
  • The 1SMA28AT3G can withstand a maximum surge current of 100 A, as specified in the datasheet. However, it is essential to ensure that the device is properly soldered and mounted to withstand such high surge currents.
  • Yes, the 1SMA28AT3G is compatible with lead-free soldering processes, as it is manufactured with a lead-free finish. However, it is recommended to follow the recommended soldering profile and temperature guidelines to ensure reliable assembly.
