SMCJ400A Frequently Asked Questions (FAQs)

  • The recommended footprint and land pattern for the SMCJ400A can be found in the Littelfuse application note AN9313, which provides guidelines for surface mount assembly of TVS diodes.
  • To ensure proper soldering, follow the recommended soldering profile and guidelines outlined in the Littelfuse application note AN9313. Additionally, use a solder with a melting point below 260°C to prevent thermal damage to the device.
  • The SMCJ400A has an operating temperature range of -65°C to 150°C, but the maximum operating temperature range for reliable operation is -40°C to 125°C.
  • While the SMCJ400A is primarily designed for transient voltage suppression, it can be used in high-frequency applications up to 1 GHz. However, the device's performance may degrade at higher frequencies due to parasitic inductance and capacitance.
  • Select the correct SMCJ400A variant by considering the required standoff voltage, peak pulse current, and package type. Consult the Littelfuse datasheet and application notes for guidance on selecting the appropriate device for your specific application.
