1KSMB47CA Frequently Asked Questions (FAQs)

  • The recommended footprint and land pattern for the 1KSMB47CA 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 maximum operating temperature range for the 1KSMB47CA is -65°C to 150°C, as specified in the datasheet. However, it's recommended to derate the device's power handling capability at higher temperatures.
  • While the 1KSMB47CA is a high-quality device, it may not meet the specific requirements for high-reliability or aerospace applications. Engineers should consult with Littelfuse or a qualified representative to determine the suitability of the device for such applications.
  • To determine the correct TVS diode, consider factors such as the working voltage, peak pulse current, and clamping voltage required for your application. Consult the Littelfuse TVS diode selection guide or consult with a Littelfuse representative for assistance.
