SM8S43A-Q Frequently Asked Questions (FAQs)

  • Bourns recommends a symmetrical PCB layout with a central ground plane, and keeping the input and output traces as short as possible to minimize parasitic inductance and capacitance.
  • Follow the recommended soldering profile and use a solder with a melting point below 260°C to avoid damaging the component. Ensure the PCB is clean and free of oxidation before soldering.
  • The SM8S43A-Q is rated for operation from -40°C to +125°C, but derating is required above 85°C to ensure reliable performance.
  • Yes, the SM8S43A-Q is designed to withstand vibrations up to 10g peak acceleration, but it's recommended to follow proper mounting and PCB design guidelines to ensure reliability.
  • Follow standard ESD handling procedures, such as using an ESD wrist strap, mat, or workstation, and ensure the PCB is properly grounded during assembly and testing.
