KBU1005G Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  A recommended PCB layout for optimal thermal performance would be to use a 2-layer or 4-layer board with a thermal relief pattern on the top and bottom layers, and a solid copper pour on the inner layers. This helps to dissipate heat efficiently.
• How do I ensure reliable operation at high temperatures?
  To ensure reliable operation at high temperatures, it's essential to follow the recommended operating conditions, provide adequate heat sinking, and use a thermal interface material (TIM) with a thermal conductivity of at least 1 W/m-K.
• What is the maximum allowable voltage stress on the device?
  The maximum allowable voltage stress on the KBU1005G is 1.5 times the maximum rated voltage (Vr) for a duration of less than 10 seconds. Exceeding this limit may cause permanent damage to the device.
• Can I use the KBU1005G in a parallel configuration to increase current handling?
  Yes, you can use multiple KBU1005G devices in parallel to increase current handling. However, it's crucial to ensure that the devices are matched in terms of their electrical characteristics and that the PCB layout is designed to minimize current imbalance and thermal mismatch.
• What is the recommended storage condition to prevent moisture-related issues?
  To prevent moisture-related issues, it's recommended to store the KBU1005G in a dry, cool place with a relative humidity of less than 60% and a temperature range of -10°C to 30°C. Avoid storing the devices in direct sunlight or near sources of moisture.
