DIODE (P/N 1n5400) - New Surplus

The 1N5400 is a silicon rectifier diode designed for DC rectification and protection in aircraft electrical systems. This general-purpose device converts alternating current to direct current in power conversion circuits and suppresses voltage spikes across relay coils in avionics applications. Install observing correct polarity—the cathode band indicates negative polarity.

Commonly used as a flyback suppression path in control circuits where inductive loads require transient protection. Follow FAA AC 43.13-1B wiring practices and component datasheet specifications during installation.

What is the DIODE (P/N 1n5400)?

The 1N5400 is a silicon rectifier diode designed for DC rectification and protection in aircraft electrical systems. This general-purpose device converts alternating current to direct current in power conversion circuits and suppresses voltage spikes across relay coils in avionics applications.

Is the 1n5400 compatible with my aircraft's avionics suite?

Avionics compatibility depends on your aircraft model and existing installation. The DIODE is available in: New Surplus. We recommend checking your aircraft's wiring diagrams and STC documentation, or contact our avionics team for compatibility assistance.

Does the 1n5400 come with an 8130-3 airworthiness tag?

Availability of an FAA 8130-3 tag depends on the part condition. Overhauled and repaired units typically include 8130-3 documentation. As-removed units may include a removal tag with trace history. Contact us for specific documentation on the condition you need.

Do you offer bench testing for the 1n5400?

We can arrange bench testing through our network of FAA-certified repair stations. Call (904) 998-9101 for testing availability and turnaround times, or submit an RFQ with your specific requirements.
