1N5821 Frequently Asked Questions (FAQs)

  • The maximum surge current rating of the 1N5821 is 150A for a single pulse of 10ms duration, as per the STMicroelectronics datasheet.
  • No, the 1N5821 is not suitable for switching applications due to its high reverse recovery time (trr) of 3μs, which can cause significant switching losses. It is recommended for rectification and freewheeling applications only.
  • The thermal resistance (Rth) of the 1N5821 is 15°C/W for the DO-201AD package, which means that for every watt of power dissipated, the junction temperature will rise by 15°C above the ambient temperature.
  • No, the 1N5821 is not suitable for high-frequency applications due to its high capacitance (CD) of 150pF, which can cause significant high-frequency losses and ringing.
  • Yes, you can use multiple 1N5821 diodes in parallel to increase the current rating, but ensure that each diode has its own separate heat sink and that the current sharing is balanced to avoid overheating and premature failure.
