1KSMB39CA Frequently Asked Questions (FAQs)

  • The recommended footprint and land pattern for the 1KSMB39CA can be found in the Littelfuse application note AN9313, which provides guidelines for surface mount assembly of TVS diodes.
  • To ensure proper soldering and avoid defects, follow the recommended soldering profile and guidelines outlined in the Littelfuse application note AN9313, and use a solder with a melting point below 260°C.
  • The 1KSMB39CA has an operating temperature range of -65°C to 150°C, but it's recommended to derate the device's power handling capabilities at higher temperatures to ensure reliability.
  • While the 1KSMB39CA is primarily designed for transient voltage suppression, it can be used in high-frequency applications up to 1 GHz, but its performance may degrade at higher frequencies due to parasitic inductance and capacitance.
  • To select the correct TVS diode, consider factors such as the maximum voltage, current, and power handling requirements of your application, as well as the desired clamping voltage and response time. Consult the Littelfuse TVS diode selection guide for more information.
