SMAJ40CA Frequently Asked Questions (FAQs)

  • The recommended footprint for SMAJ40CA is a standard DO-214AC package with a pad size of 2.5mm x 1.5mm and a spacing of 1.5mm between pads.
  • To handle thermal considerations, ensure a good thermal connection to the PCB, use a thermal pad or a heat sink if necessary, and follow the recommended PCB layout guidelines to minimize thermal resistance.
  • The maximum allowable voltage for SMAJ40CA is 40V, but it's recommended to derate the voltage to 30V or less for reliable operation and to prevent overheating.
  • SMAJ40CA is not recommended for high-frequency circuits (>1MHz) due to its internal capacitance and inductance. For high-frequency applications, consider using a different TVS diode with lower capacitance and inductance.
  • Select the correct SMAJ40CA by considering the maximum voltage, current, and power requirements of your application. Also, ensure the device meets the required standards and certifications (e.g., IEC 61000-4-5) for your industry.
