SSQE48T07120-NABNG - BelFuse

SSQE48T07120-NABNG Frequently Asked Questions (FAQs)

• What is the recommended PCB layout and thermal management for optimal performance?
  Bel Fuse recommends a PCB layout with a solid ground plane and thermal vias to dissipate heat. A minimum of 2 oz copper thickness is recommended. Additionally, a thermal interface material (TIM) can be used to improve heat transfer between the device and the heat sink.
• How do I ensure reliable operation in high-vibration environments?
  To ensure reliable operation in high-vibration environments, Bel Fuse recommends securing the device using a screw-down or clip-down method. Additionally, the PCB should be designed to minimize flexure and vibration transmission to the device.
• What are the derating guidelines for high-temperature operation?
  Bel Fuse recommends derating the device's power rating by 1.5% per degree Celsius above 40°C. For example, at 60°C, the power rating would be derated by 30% (1.5% x 20°C).
• Can I use this device in a parallel configuration to increase power handling?
  Yes, the SSQE48T07120-NABNG can be used in a parallel configuration to increase power handling. However, it is essential to ensure that the devices are properly matched and that the PCB layout is designed to minimize current imbalance and thermal gradients.
• What are the recommended soldering and rework conditions for this device?
  Bel Fuse recommends soldering the device using a peak temperature of 260°C for 10 seconds or less. For rework, a maximum of 3 reflows is recommended, with a peak temperature of 240°C for 10 seconds or less.
