1KSMB12A Frequently Asked Questions (FAQs)

  • The recommended footprint and land pattern for the 1KSMB12A 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 1KSMB12A 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 1KSMB12A 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 1KSMB12A 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.
