SP3400-02UTG - LITTELFUSE

SP3400-02UTG Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance of the SP3400-02UTG?
  A good PCB layout for the SP3400-02UTG 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 SP3400-02UTG handle surge currents and what is the maximum surge current it can withstand?
  The SP3400-02UTG is designed to handle high surge currents. It can withstand a maximum surge current of 3A (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 SP3400-02UTG and how does it affect the device's performance?
  The SP3400-02UTG 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 SP3400-02UTG be used in automotive applications and what are the relevant certifications?
  Yes, the SP3400-02UTG is suitable for automotive applications. It meets the requirements of ISO 7637-2 and is certified to IEC 61000-4-2 (ESD) and IEC 61000-4-4 (Electrical Fast Transients).
• How does the SP3400-02UTG compare to other TVS diodes in terms of clamping voltage and response time?
  The SP3400-02UTG has a relatively low clamping voltage of 14.5V (max) and a fast response time of <1ns. This makes it suitable for protecting sensitive electronics from voltage transients and surges.
