1.5SMC440A Frequently Asked Questions (FAQs)

  • The recommended footprint and land pattern for the 1.5SMC440A 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 1.5SMC440A 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 to ensure reliable operation.
  • Yes, the 1.5SMC440A can be used in high-frequency applications, but its performance may degrade above 1 GHz due to internal capacitance and inductance. For high-frequency applications, consider using a TVS diode with a lower capacitance and inductance, such as the 1.5SMCJ440A.
  • To select the correct TVS diode, consider the following factors: voltage rating, peak pulse current, clamping voltage, and response time. Consult the Littelfuse TVS diode selection guide or contact a Littelfuse application engineer for assistance.
