SP1001-04XTG - LITTELFUSE

SP1001-04XTG Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance of the SP1001-04XTG?
  A good PCB layout for the SP1001-04XTG involves keeping the input and output traces separate, using a solid ground plane, and minimizing the distance between the TVS diode and the protected circuit. A 4-layer PCB with a dedicated ground plane is recommended.
• How does the SP1001-04XTG handle surge currents and what is the maximum surge current it can withstand?
  The SP1001-04XTG is designed to handle high surge currents. It can withstand a maximum surge current of 100A (8/20μs) and is certified to IEC 61000-4-5 (Lightning) and ISO 7637-2 (Automotive) standards.
• What is the operating temperature range of the SP1001-04XTG and how does it affect the device's performance?
  The SP1001-04XTG operates over a temperature range of -40°C to 150°C. The device's performance remains stable across this range, but the leakage current may increase at higher temperatures.
• Can the SP1001-04XTG be used in high-frequency applications, and if so, what are the limitations?
  Yes, the SP1001-04XTG can be used in high-frequency applications up to 1 GHz. However, the device's performance may degrade at frequencies above 100 MHz due to parasitic inductance and capacitance.
• How does the SP1001-04XTG respond to repetitive surges and what is the recommended derating factor?
  The SP1001-04XTG is designed to withstand repetitive surges. A derating factor of 0.7 is recommended to ensure the device's reliability and prevent thermal runaway.
