IT155 - Schaffner

IT155 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance of the IT155?
  Schaffner recommends a symmetrical PCB layout with a solid ground plane, and keeping the input and output traces as short as possible to minimize electromagnetic interference (EMI).
• How do I ensure the IT155 is properly cooled in my application?
  The IT155 has a built-in thermal pad for heat dissipation. Ensure good thermal contact between the pad and a heat sink or metal plate, and provide adequate airflow around the component.
• What is the maximum surge current the IT155 can withstand?
  The IT155 can withstand surge currents up to 100 A (8/20 μs) according to IEC 61000-4-5, but this may vary depending on the specific application and installation.
• Can I use the IT155 in a redundant or parallel configuration?
  Yes, the IT155 can be used in redundant or parallel configurations, but ensure that the total current rating is not exceeded and that the components are properly synchronized to avoid oscillations.
• How do I select the correct IT155 variant for my specific application?
  Select the IT155 variant based on the required current rating, voltage rating, and filter type (e.g., single-stage or two-stage). Consult Schaffner's application notes and technical support for guidance.
