SMF33A Frequently Asked Questions (FAQ)

  • The recommended footprint and land pattern for SMF33A can be found in the Littelfuse application note AN9313, which provides guidelines for surface mount assembly of TVS diodes.

  • To ensure reliability in high-temperature applications, it is recommended to derate the power rating of SMF33A according to the temperature derating curve provided in the datasheet. Additionally, ensure that the device is properly soldered and that the PCB is designed to minimize thermal resistance.

  • Yes, SMF33A can be used in high-frequency circuits. However, it is essential to consider the parasitic inductance and capacitance of the device, which can affect the circuit's performance at high frequencies. It is recommended to use a suitable PCB layout and component selection to minimize these effects.

  • To select the correct SMF33A variant, consider the maximum voltage, current, and power requirements of your application. Refer to the datasheet to determine the suitable variant based on the breakdown voltage, peak pulse current, and power dissipation ratings.

  • SMF33A provides ESD protection up to ±30kV air discharge and ±30kV contact discharge, according to the IEC 61000-4-2 standard. This makes it suitable for protecting sensitive electronics from electrostatic discharge events.
