BR66 - GeneSiC Semiconductor

BR66 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  GeneSiC recommends a 2-layer or 4-layer PCB with a thermal pad connected to a large copper area on the bottom layer to dissipate heat efficiently. A minimum of 2 oz copper thickness is recommended.
• How do I ensure reliable operation at high temperatures?
  Ensure proper heat sinking, use a thermally conductive material for the heat sink, and maintain a maximum junction temperature (Tj) of 150°C. Also, follow the recommended derating curves for current and voltage.
• What is the maximum surge current rating for the BR66?
  The BR66 can withstand surge currents up to 10 times the rated current (Ic) for a duration of 10 ms. However, it's essential to follow the recommended surge current derating curves to ensure reliable operation.
• Can I use the BR66 in a parallel configuration to increase current handling?
  Yes, the BR66 can be used in parallel configurations, but it's crucial to ensure that the devices are matched in terms of current sharing and thermal performance. GeneSiC recommends using a current sharing scheme, such as a master-slave configuration, to ensure reliable operation.
• What is the recommended gate drive voltage and current for the BR66?
  GeneSiC recommends a gate drive voltage of 15-20 V and a current of 1-2 A to ensure fast switching times and low losses. However, the actual gate drive requirements may vary depending on the specific application and circuit design.
