SSL4120T/1,518 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  A 2-layer or 4-layer PCB with a solid ground plane and thermal vias is recommended. Ensure a minimum of 1 mm clearance around the device for airflow and heat dissipation.
• How do I ensure reliable operation at high temperatures?
  Implement a proper thermal management system, including a heat sink and thermal interface material. Ensure the device is operated within the recommended temperature range (TJ = -40°C to 150°C).
• What is the maximum allowed voltage on the input pins?
  The maximum allowed voltage on the input pins is 6.5V. Exceeding this voltage may damage the device.
• How do I minimize electromagnetic interference (EMI) in my design?
  Use a shielded enclosure, keep sensitive components away from the SSL4120T, and ensure proper grounding and decoupling. Follow good PCB design practices, such as using a solid ground plane and minimizing trace lengths.
• What is the recommended input capacitor value and type?
  A 10 μF to 22 μF X7R or X5R ceramic capacitor is recommended for input decoupling. The capacitor should be placed as close to the device as possible.
