SZMMSZ4678T1G Frequently Asked Questions (FAQs)

  • A thermal pad is recommended under the package to improve heat dissipation. A minimum of 2oz copper thickness and a thermal relief pattern are suggested. Refer to onsemi's application note AND8031/D for more details.
  • Ensure the device is operated within the recommended junction temperature (Tj) range of -40°C to 150°C. Implement proper thermal management, such as heat sinks or thermal interfaces, to maintain a safe operating temperature.
  • Handle the device with ESD-protective equipment and follow proper handling procedures to prevent damage. The device has built-in ESD protection, but it's not a substitute for proper handling and storage procedures.
  • The SZMMSZ4678T1G is an industrial-grade device, but it's not specifically designed for high-reliability or automotive applications. For such applications, consider using devices with specific automotive or high-reliability qualifications, such as AEC-Q101 or MIL-PRF-19500.
  • Follow the recommended soldering profile: peak temperature 260°C, time above 217°C 60s max. For rework, use a low-temperature soldering iron (<350°C) and avoid applying excessive force or heat to the device.
