1N5408 Frequently Asked Questions (FAQs)

• What is the maximum surge current rating of the 1N5408?
  The 1N5408 has a maximum surge current rating of 200A for a single pulse of 10ms duration.
• Can I use the 1N5408 for switching applications?
  No, the 1N5408 is not suitable for switching applications due to its high reverse recovery time (trr) of 3μs. It's primarily designed for rectification and voltage regulation.
• What is the thermal resistance of the 1N5408?
  The thermal resistance (RθJA) of the 1N5408 is 25°C/W, which means it can dissipate heat efficiently.
• Is the 1N5408 suitable for high-frequency applications?
  No, the 1N5408 is not suitable for high-frequency applications due to its high capacitance (CP) of 120pF, which can cause unwanted resonance and noise.
• Can I use the 1N5408 in a parallel configuration to increase current handling?
  Yes, you can use multiple 1N5408 diodes in parallel to increase the current handling capacity, but ensure proper current sharing and thermal management.
