DIODE (P/N in4001) - New Surplus

The in4001 is a silicon rectifier diode that allows current to flow in one direction while blocking reverse current. It suppresses flyback voltage across relay coils and inductive loads in DC control circuits throughout aircraft electrical systems. Install with correct polarity per your aircraft wiring diagram and maintenance manual.

This diode meets aerospace standards and is used in avionics, lighting control, and instrumentation circuits where protection from voltage spikes is required.

What is the DIODE (P/N in4001)?

The in4001 is a silicon rectifier diode that allows current to flow in one direction while blocking reverse current. It suppresses flyback voltage across relay coils and inductive loads in DC control circuits throughout aircraft electrical systems.

Is the in4001 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 in4001 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 in4001?

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.
