SMM4F28A-TR Frequently Asked Questions (FAQs)

  • STMicroelectronics recommends a thermal pad on the bottom of the package, connected to a large copper area on the PCB to dissipate heat efficiently. A minimum of 2oz copper thickness is recommended.
  • Ensure that the device is operated within the recommended junction temperature range (TJ) of -40°C to 150°C. Implement proper thermal management, and consider using a heat sink or thermal interface material if necessary.
  • STMicroelectronics recommends a soldering profile with a peak temperature of 260°C, a dwell time above 217°C of 60-90 seconds, and a total process time of 3-5 minutes.
  • Store the devices in their original packaging, away from direct sunlight, moisture, and extreme temperatures. Avoid bending, flexing, or twisting the leads, and handle the devices by the body, not the leads.
  • The SMM4F28A-TR has built-in ESD protection, but it's still recommended to follow standard ESD handling procedures, such as using an ESD wrist strap or mat, and storing the devices in anti-static packaging.
