SMAJ78A Frequently Asked Questions (FAQs)

  • The recommended footprint and land pattern for SMAJ78A can be found in the Littelfuse application note AN9313, which provides guidelines for surface mount assembly of TVS diodes.
  • To ensure reliability, it's essential to follow the recommended derating curves for voltage and current, and to consider the device's thermal resistance and power dissipation. Additionally, ensure that the device is soldered correctly and that the PCB is designed to minimize thermal stress.
  • While SMAJ78A is primarily designed for transient voltage suppression, it can be used in high-frequency circuits. However, the device's capacitance and inductance should be considered, and the circuit should be designed to minimize resonance and ringing.
  • Select the correct SMAJ78A variant by considering the maximum voltage, current, and power requirements of your application. Refer to the datasheet and consult with Littelfuse's application engineers if necessary.
  • SMAJ78A provides ESD protection up to ±30kV air discharge and ±30kV contact discharge, meeting the requirements of IEC 61000-4-2.
