RB521G-40FHT2R Frequently Asked Questions (FAQ)

  • ROHM recommends a thermal pad size of at least 2.5mm x 2.5mm, with multiple vias to the ground plane to ensure efficient heat dissipation. A thermal resistance of less than 10°C/W is achievable with a well-designed PCB layout.

  • To ensure reliability, follow the recommended operating temperature range (TJ) of -40°C to 150°C. Implement proper thermal management, such as heat sinks or thermal interfaces, and avoid exceeding the maximum junction temperature (TJ) during operation.

  • ROHM recommends a soldering profile with a peak temperature of 260°C, a dwell time above 240°C of 20-30 seconds, and a total process time of less than 60 seconds. This ensures reliable solder joints and minimizes thermal stress on the device.

  • While the RB521G-40FHT2R is not specifically designed for high-humidity environments, it can still be used with proper precautions. Ensure the device is stored and operated in a dry environment, and consider applying a moisture-resistant coating or conformal coating to protect the device from moisture ingress.

  • To troubleshoot issues, start by verifying the device's operating conditions, including voltage, current, and temperature. Check for proper PCB layout, thermal management, and soldering quality. Use oscilloscopes or other diagnostic tools to identify anomalies, and consult ROHM's application notes and technical support resources for guidance.
