SIHFR9014-GE3 datasheet by Vishay Siliconix

SIHFR9014-GE3 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  Vishay recommends a PCB layout with a large copper area connected to the tab of the device to improve thermal dissipation. A minimum of 1 oz copper thickness is recommended, and the use of thermal vias can further enhance heat transfer.
• How do I ensure reliable soldering of the device?
  To ensure reliable soldering, follow the recommended soldering profile: peak temperature of 260°C, time above 217°C of 30 seconds, and a soldering iron temperature of 350°C. Use a solder with a melting point above 217°C, and avoid using excessive solder or flux.
• What is the maximum allowed voltage imbalance between the input and output?
  The maximum allowed voltage imbalance between the input and output is ±10% of the rated voltage. Exceeding this limit may affect the device's performance, reliability, or even cause damage.
• Can I use this device in a high-reliability or aerospace application?
  While the SIHFR9014-GE3 is a high-quality device, it is not specifically designed or qualified for high-reliability or aerospace applications. For such applications, consider using devices with specific certifications, such as MIL-PRF-19500 or ESCC, and consult with Vishay's application engineers for guidance.
• What is the device's behavior during a short-circuit event?
  In the event of a short-circuit, the SIHFR9014-GE3 is designed to withstand the fault current for a short duration. However, prolonged short-circuit conditions can cause damage to the device. It is essential to implement proper overcurrent protection and fault detection mechanisms in the system design.
