FSBB15CH60 Frequently Asked Questions (FAQs)

• What is the maximum allowed voltage imbalance between the DC bus and the AC output?
  The maximum allowed voltage imbalance is typically ±10% of the rated DC bus voltage. Exceeding this limit can lead to uneven current sharing and reduced module reliability.
• How do I ensure proper thermal management and heat sinking for this module?
  Proper thermal management involves ensuring good thermal contact between the module and the heat sink, using a thermal interface material (TIM) with a thermal resistance of ≤ 0.1°C-in²/W, and maintaining a maximum junction temperature (Tj) of ≤ 150°C.
• What is the recommended gate resistance (Rg) value for this module?
  The recommended gate resistance (Rg) value is typically between 10 Ω and 20 Ω. A lower Rg value can reduce switching losses but may increase the risk of oscillations, while a higher Rg value can reduce oscillations but may increase switching losses.
• Can I use this module in a parallel configuration to increase power handling?
  Yes, but with caution. Parallel operation requires careful consideration of current sharing, thermal management, and gate drive synchronization to ensure reliable operation. Consult onsemi's application notes and technical support for guidance.
• What is the maximum allowed dv/dt and di/dt for this module?
  The maximum allowed dv/dt is typically ≤ 10 kV/μs, and the maximum allowed di/dt is typically ≤ 100 A/μs. Exceeding these limits can lead to premature aging or failure of the module.
